  2. Hello, I have a 1999 Chevy Express conversion van. It has very low miles on it. It has the Winnebago conversion package from Chattanooga, TN. It was supposed to have the 34 gallon tank per the conversion documents but only has the 31 gallon tank. I would like to add a secondary tank where the spare tire is located under the body and behind the rear axle. Has anyone found a company that makes such a tank? If so, can you provide me with the link? Thanks!
  3. So I have a 2018 Silverado 5.3 Z71 LT and I've tried looking up threads for this topic before but for some reason I haven't had any luck. Ive had this truck for a year now and I had a level lift installed and my MPG stayed around 18-22 MPG and I could get 325-400 miles out of a full tank of fuel. I recently installed a 3.5 Rough Country suspension lift and I installed 20" wheels with 33" tires. I knew going into this modification that I would see a slight decrease in MPG but immediately after the install I dropped my MPG to 7.5-9 MPG and I cannot get it to increase AT ALL. I used to work at a GM dealership and spoke to a couple of old co-workers about this issue and for some reason we cannot pinpoint the issue. I know that increasing the ride height and the different wheel/tire package would create a difference but I didn't know that it would be this bad. I'm considering a performance chip and a CAI to try and increase my MPG, and its not a bad batch of gasoline and I've changed my driving habits and kept my foot off the throttle a little bit...if anyone has any info on this it would be greatly appreciated, thanks a lot!!
  4. Hello everybody from sunny Saskat-chewan. I have a 2000 GMC C6500 topkick (former U-hauler) and I would like to lock my fuel tank (60 gal - gasoline | 7.4l V8) away from prying hoses. I'm going to drill and tap the cap, and put in an allen-key set screw but I'd prefer a regular keyed arrangement. Any comments on this topic, preferably with a locking cap solution? The only locking caps I see around have a male thread - my truck requires a cap with female threads. Thanks in advance, Keep On Truckin'!
  5. Afternoon ladies and gents. I have spent hours upon hours trying to do my homework here on the GM 6.0 gasser engines. I have been around diesels the past 6 years, love my current tow rig. (2013 Ram 2500 Tradesman w/ 6/7 cummins) Truck is stock no deletes. What brought me here is we have our first baby on the way, the thought of saving some money by trading down to a gasser seems like a good idea. But i am not sure with how often i tow that i will be happy. I live in Illinois and tow a 28 ft enclosed racecar hauler throughout the state (mostly flat). I tow every weekend from April to October generally, the trailer weighs close to 8K loaded. Obviously the cummins tows this with zero issues, and i'm assuming the GM 6.0 would tow this fine as well. I found a 2009 Chevy 2500 that's loaded with 110,000 miles on it. It appears to be in great shape, from what i found out it has the LY6 engine. If i were to make the switch i'd free up over 100 bucks a month, but is that really enough to justify the switch? I'm not in a bind for money at the moment, but obviously saving some money never hurts. I guess i'm basically looking at some opinion's from guys that have maybe made the switch from a diesel to a gasser, and see what there thoughts were? Or do i tow enough that i should just stick it out with the diesel? Looking forward to your thoughts! *Also, i would estimate that based on my location and where i'm traveling i drive roughly 3500-4000 miles a year with the trailer hooked up.
  6. 2015 Silverado, 5.3 Gas with just under 34,400 miles. I've just started noticing that ??burnt oil?? smell after starting the truck up. Usually after sitting all day at work, or overnight in the garage. Only way I can describe the smell is by the 2003 Silverado I drove at work for years that ended up having a new engine put in it. I don't see any puff of bluish/white cloud on startup. Only noticed it like in the last week. Usually I'm either remote starting it when it's cold out or getting in and starting it up. So I never smell it. It's only 16 miles round trip to and from work with many more stop and go's than miles. It only had just under 11k when I bought it in Aug 2017. So what, 23k in 18-19 months. It runs smooth, idles smooth. Should I worry about it? The way things have been going lately, it would be just my luck to have a screwed up engine.
  7. I smell raw gas when approaching my tailgate. i don’t smell it any where else. what would cause this? on a 2014 GMC Sierra Denali 5.3L
  8. I have over 2,200 miles on my truck and really like it. A few minor issues: My gas gauge hits E and low fuel light comes on after consuming 21 gallons. So, I have over 5 gallons and approx. 100 miles left before running out. This is about 2 gallons too early IMO. Is anyone else experiencing this? Also, I have a few times where the indicator lights don't come on my heated seat buttons. The seats still heat up, just no lights. After adjusting the volume from the steering wheel, the volume graphic will sometimes stay on the display in the dash. After remote starting, I will enter the cab and after hitting the start button, a warning will appear on the display: "Service Steering Column Lock". I'll hit the check mark to dismiss and it goes away. I hope they come up with fixes for these items. Thanks.
  9. I stumbled upon a local BP Gas station here in the KC area that sells a 100% No Ethanol Fuel (93 octane). It is $.20 per gallon more than the 93 octane with 10% Ethanol. I thought I would try a couple of tanks out to see if MPGs would further increase. Anyone out there have a similar option in their area that can chime in on results good or bad?
  10. Hey guys, been searching but haven't found a simple way to look this up. I have a 2008 Silverado 2500 HD 6.0 Gas, extended cab, 8 foot bed, I am reasonably sure its a 3.73 axle ratio and it has the towing package. The truck has almost 180k on it and the rear diff cover is leaking (seeping through). What I want to get is: http://www.taperformance.com/proddetail.asp?prod=TA_1803 Has one on my old truck, its a nice piece. However I see that they only make it for a 9.5" ring gear. I see that my truck could be 9.5, 10.5, or 11.5. How do I go about identifying it?
  11. Hey guys, I was curious to hear what you all have done on your truck for better gas mileage and what you think the best grade of gas is to use for gas mileage. I have a 2017 Silverado custom and get about 19 average.
  12. Does anyone run E15 88 octane gas on a regular basis? I know it is at stations in MN, not sure how widespread it is, but it's a 15% ethanol blend (vs 10% normal) and is a little bit cheaper. It says its OK for all vehicles and trucks 2001 or newer. Just wondering if anyone runs it on a regular basis or has evaluated the mileage they get with it vs other gas options. http://mnfuels.com/e15.cfm
  13. I have a 2004 Subura Impreza.All of a sudden it takes almost 10 minutes or so to pump $10.00 into it.I need help with this.I just had a new gas tank put in etc. Can somebody give me advice on how to fix this? Thank you.
  14. Good morning everyone, This is my first post ever, and the first time I have "started a thread." I am reaching out because I am having an issue with my 14 Silverado All Star edition, and I just dropped It off at the Dealer I bought it from today. This truck is my first Domestic purchase over the past 20 years since I started driving. I have always had Foreign, mostly German cars, and I have been working in Dealerships basically since I was in High School. I also have never worked for a Domestic manufacturer, maybe that's why this is the first Domestic product I have bought. Everything started about a week ago when I got into my truck to leave work and I immediately noticed a strong gas/fuel smell in the cabin. At first I thought it was a car in front or behind me, maybe even the area I was in, but the smell was there for the entire 30 minute ride home. Over the next few days the same thing happened several times. Over the past weekend I popped the hood and it was like a punch in the face! The fuel smell was definitely coming from the engine bay, and right into the cabin. I tried putting the A/C on, rolling down the windows, and shutting off the outside air. Didn't make much of a difference, still too strong to drive around. After talking to a few of my Techs at my store, and other people in the Automotive industry, I found someone at a Chevy Dealer that told me there was an "Internal Bulletin" from the manufacturer that said there could be some 2014 models with a this concern. The bulletin has not gone public as of right now so not many people have heard of it. Even the Chevy store across the street from my store had no clue. But luckily I found someone at the Dealer I bought the truck from that actually cared enough to do 60 seconds worth of research. I have heard stories of injector seals not seated correctly and fuel is actually coming out from there, also maybe the fuel pump on the motor has a leak, but not sure yet. Hopefully I will hear soon as to what the Dealer found so I can get my truck back and not have to drive a Chevy Cruz that barely fits two people comfortably. So I am wondering if anyone has had any experience with this... And if anyone is interested I can keep you posted as my situation progresses.
  15. Hello, I've read a lot of good information on here so I'd figured I would ask a question. I have a 2006 GMC Sierra with 288k and it is the best truck I've ever bought, however, I feel it is time to switch to a newer Sierra. I'm looking for a 2014, 2015 or 2016 Sierra 1500 with the 5.3L AWD and Crew Cab. Which model year is better as far as bugs and issues and why do you recommend it? Thanks
  16. All, I am looking into getting a 2006 Silverado 2500HD 2wd LT with the 6.0. It's a Single cab long bed work truck. I pulled the VIN info and found that it has always been in Tucson and Cali. The truck has no rust (as to be expected). The only noticable problem is the Oil Pressure Sensor seems to be dead, (easy $50 fix). Anyhow, I have never worked with or on a 2500 before, and would like to know what I should look for before purcasing the truck. Also, what do you all think is a good price for a truck like this? I am gonna be using this truck for slight hauling and pretty much daily driving.
  17. What programmer is better for fuel economy? From what I've seen bullydog has a better MPG increase but I've also seen that you have to run 91 octane. Is that true? I've always had a diesel before this so i don't know much about the gas tuners so really I'm just wondering what you guys think is the better buy and why. Thanks!!
  18. Hello all! Im new to the whole forum thing but at this point, ive become desperate. I have a 2008 silverado 2500hd gasser. i bought the truck maybe a year and a half ago and it has had a check engine light since the day i bought it, never really bothered me much and i just cleared the code temporarily to get it inspected in NJ. the problem hasn't become any worse. its just now becoming more and more of a hassle as the weather cools down. I have the code PO449 the truck also leaks a good amount of gas when you fill it up. maybe a cup? it leaks from the top of the tank and runs down both sides of the tank Ive read up on the code and many people blame either the gas cap, or the purge solenoid, or the evap valve or something like that. i replaced this part http://www.partsgeek.com/vrwkl6g-chevrolet-silverado-1500-vapor-canister-vent-solenoid.html?utm_source=nextag&utm_medium=pf&utm_content=dc&utm_campaign=PartsGeek+Nextag&fp=pp&utm_term=Chevrolet+Vapor+Canister+Vent+Solenoid in doing so, i ripped one of the lines going into the canister. the leak continued so i tried to RTV the hole that was caused, seemed to adhere just fine. (Let me also mention, the truck was totaled before i bought it and then was reconstructed. rear end accident. everything looks good now but I'm sure thats what caused this whole thing) so the Vapor Canister Vent Solonoid didn't fix the issue. i then decided i should try to lift the bed and look at the top of the tank, maybe find where this is coming from. the nuts that are welded onto the frame that the bed then bolts to are rusted and one snapped off, so for now, getting the bed off is kinda out of the question. i have to freeze frame shots of my system from when the Check engine light was triggered. please take a look and help me if you can, id really appreciate any help at this point. Thank you do much
  19. I just ordered a Bully Dog Platinum GT Tuner and have heard some good things about it, for an 08 Silverado 1500, with a 5.3 what gains in horsepower and torque should i be getting and how noticeable will it be? Also what will my fuel economy be like with the tuner all on performance settings (right now I get about 14 on 32's?
  20. Hi guys. Was wondering if anyone had a easy way to keep a check on fuel octane levels? I saw this Russian made device OKTIS-2 http://www.ebay.com/itm/PORTABLE-FUEL-OCTANE-NUMBER-ANALYZER-TESTER-METER-OKTIS-2-NEW-/161886552305 looked like it would be useful for keeping an eye on octane levels and it is cheap (under 100 bones). looks like you just stick it in the tank and then pump some fuel through it, seems rather ingenious but not sure how accurate the thing would be? The reason I am looking is that I recently installed a canned tune from a hand held programmer for premium fuel 91 plus octane in my 16 Denali 6.2 I buy Shell 93 octane and the truck has run great for the first week after that premium fuel tune install but after I filled back up with Shell 93 octane last Thursday the next morning on the way to work I got the "reduced engine power" warning on my dash anytime the engine was over 3000rpm. I suspect that the fuel was BAD from my local Shell station but have no way to prove that...... I went back to stock tune friday afternoon and the issue is gone but now I do not want to use the premium tune without verifying that I am actually getting 91 octane or better fuel. Note: Gas line was busted in AL a couple of weeks back and Middle TN has suffered from spotty shortages of fuel (most notably premium fuel) I suspect that my local Shell had regular fuel loaded into their premium tank. (could have been a mistake) my plan is to run this tank all the way down to just a few gallons and then hopefully have a tester in hand and fill back up with REAL premium 91 plus octane fuel. Anyone got one or have something else that they use?
  21. Hello, I have a 2015 Chevy Silverado 1500LT 5.3L V8 Midnight Edition. Can someone explain to me the proper usage of 4WD? I haven't had to turn it on until today when the snow was bad. The problems I experienced were that the truck would basically not work in reverse with 4WDHI engaged. When I was backing out of my driveway with 4WDHI engaged, I would press on the accelerator and it would move somewhat, though really slowly and it didn't seem correct. This was the first time I had really used 4x4 on this truck so I didn't think anything of it. Well after driving an hour to work with 4x4HI engaged, through backroads and highway, I had to back into my parking spot and it wouldn't do it. I pulled up and put it in reverse and cut the wheel and it didn't really go anywhere proportionate to the amount of gas I was giving it. So I switched it to 2WD and it worked like a charm. I doubt something is wrong with the truck so I'm hoping someone can explain to me how this is to be properly used and what the desired functionality is. If it's not good to shift the drive in motion, I'm expected to change it to 2WD whenever I want to reverse? What if the lot wasn't plowed and snow was so thick I really needed the 4WD to reverse? Any help would be appreciated thanks.
  22. So, a couple months back I installed the Magnaflow cat-back, single in/dual out, exhaust system on my 2015 2500HD 6.0L Sierra (see some info/pics on the install and outcome below). http://www.gm-trucks.com/forums/topic/171270-2015-60-muffler/page-2?do=findComment&comment=1673626 Truly I am quite happy with it. Got a great deal online, sounds great, was able to install it myself with no major issues, got the dual tips perfectly aligned, etc... Fast forward about 2,000 miles. Still love it, however after moving it in my driveway I recently noticed a 3rd wet spot underneath my truck about the same size/shape/color as what had resulted in water dripping from the exhaust tips. So, I got underneath and noticed that some water was dripping from both outlet ports from the muffler. Now, the drips on each side are coming from where you clamp the rear pipes to the muffler outlets. Worth mentioning: periodically since installing, I have gotten back under the truck and checked every nut and bolt for loosening and re-tightened where necessary. There was some very slightly that tightened more after about 50-100 miles but absolutely none since then. Also worth mentioning: the outlet ports on the rear of the muffler are basically exhaust pipe diameter and stick out roughly 1", which is what you connect the exhaust pipe to, and clamp down on. The 1" that sticks out obviously is not a perfect tube; the welding imperfections stick out 1/4"-1/2". I did not want to clamp the exhaust pipe down to only half, or the tip, of the outlet port, so it is partially clamped down over welded material. I believe this is obviously why there is some water leaking, but I saw no way to avoid this. I found the point where I thought the pipe was clamped on just enough to be as solid as possible, which meant MAYBE a few mm's of weld bumps, and tightened the hell out of it. My question: how big of a problem is this small water leak, does it largely effect backpressure, performance, etc.? I am not very knowledgeable on exhaust systems as my last one was done at a local shop, but the only solution I can see is taking it to a shop and having them weld those pieces together to eliminate this issue. At that point, might they as well weld each connection together? Anyone have any other suggestions? Any and all feedback or insight is appreciated. I am pretty sure I know what a shop will tell me to do, but hoping to get the real scoop here first! Thanks!!!!
  23. My gas Gage will randomly drop to below "E" Randomly then if bang the tank or somtimes even stomp my foot on the floor it will go back to normal, before i drop the tank i was wondering if anyone had any ideas what it could be ???
  24. I would be thankful to anyone who could help me figure out how to get more fuel capacity on a 2015 Chevy 1500 4 door 6.6 box. I know the 2 door models had the option of a 34 gal tank but i having a very hard time finding anything for the truck I own. I tow a light camper and am usually with a family member with a motor home with a 1800 mile range so stopping every 250 or so miles is getting really annoying. Also yes I would have loved to get a 2500HD but it just didn't happen so im trying to make the best with what I have.
