Weekend update on the install: Everything seems to doing fine! I will likely fill the tank to the brim later this week; I added another 10 gallons without drama. It's weird watching the range mon

When I bought my 2024 LT Trail Boss with the short bed the salesman said it had a 28 gal tank. I asked for the build sheet, which didn’t show any detailed specs nor the gas tank size. Can anyone confirm if the new 2024’s have a larger gas tank?

I received an email from LRA today.  They are willing to ship a tank to me for $1,999 plus $195 in shipping.

Interesting comment. I tried searching this forum before posting initially but found very little on the subject which is why I posted in the first place. I’m curious why you state it was “dismissed as not feasible”. Seems totally feasible to me if a aftermarket company offers a larger fuel tank for the same truck which is diesel powered and whose numbers are a fraction of the gas powered counterparts…. What am I missing Bikerjon? Who wouldn’t want the ability to go 600+ miles between fuel stops as opposed 380 or so?

 

 

Sounds great. Maybe you and Elbow joe can split the shipping.

I'm tempted, but not ready.  190L = 50 gallons.  That's 750 miles capacity at 15mpg and 1,000 miles at 20mpg.  I've seen over 20 mpg on some trips.  Looking at pics the aluminum driveshaft seems very close to the gas tank.  Might be a good idea to spend another $2k to get the steel driveshaft.  Now the only other question that needs to be answered is how to recalibrate the fuel gauge so it shows correctly.

Just a thought.... I see people selling 2500 fuel tanks on ebay... Couldn't you just swap in the 36 gal tank? 

Would it fit?  Pics on Ebay show a tank that appears to be much taller.  If it did fit the cost difference would be much more effective versus the 50 gallon tank from Australia.  The difference is only $200 after you sell your stock tank, plus shipping charges.  Still, my previous question wasn't answered and is still just as applicable to this scenario.  Would the truck's computer function properly?  Now I'm asking a new question along with the previous one.  Would the fuel pump for the 1500 fit in the 36 gallon tank, or would the fuel pump for the 36 gallon tank work with our truck?

A little research tonight revealed the fuel guage measurements on the stock sending unit is analog.  When it comes to the amount of fuel in the tank as a fraction it'll read correctly on the dial in the dash.  As for distance, I'm still unsure.  I assume the computer programming contains a simple mathematical equation utilizing the fuel tank capacity in it.  Reprogramming would only mean changing the fuel tank capacity number for a correct range readout.  I haven't looked into the dimensions of tank, specifically depth, so I don't know yet if the stock sending unit will function when the fuel level gets low.  I'm only looking into this here and there and only curious at this point.  A larger fuel tank is not a high priority for me right now.  If anybody else is looking into this and gets some answers it would be appreciated if they posted that info.

I have a few fills at over 700 miles, and lots at over 600 miles - '23 3.0L crewcab/4wd/6.5ft 

It range is a serious issue, the 3.0L is your friend. 

Fwiw, I got about 20-21 doing same job with a '16 5.3 crew/4wd/6.5ft

I have a 2019 RST with a 5.3 V8 gas. The fuel tank is 24 gallons. The fuel fill was clearly made for a diesel as it has a fill hole and a big open space for a def tank in front of the gas tank. I hate having to stop every 1.5-2 hours to fill up when I’m towing my camper knowing that there’s plenty of space for a tank with much greater capacity.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      By KARNUT · Posted

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
