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?

So did you ever put a bigger tank in your truck?

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

I filled the tank today. I was running errands when I got the "Low Fuel" warning. I stopped and fueled it up to the brim. Some quick math:

  • Remaining Range Indicated = 50 (multiply by 2 to get a real ballpark of range with the 50-gallon tank)
  • Recent Avg MPG = 16.8
  • Calculated fuel in tank = 50(2)/16.8 = 5.95 gallons
  • Tank took 43.5 gallons per the pump
  • 5.95+ 43.5 = 49.45 gallons total 
  • ~.5 gallon is not accounted for in the range calculation.

I'm surprised that there is only .5 gallon not accounted for in the calculations - the gauge is extremely accurate.

 

Photo from pump; I went to one of the cheaper places in town at $3.01/gallon

That's not 93 octane is it?  93 octane in west Florida is about $1 more.

Different states have widely varied retail prices for gas. Cost of supply, transport, and state tax are some of the variables. The post isn't about the price of gas - it's about the freedom of range the larger tank has.

Latest fill was with 725 miles on the tank at 15.8 mpg indicated. Took 45.4 gallons (US) and range indicated at 40 miles (~80 actual). 

Zero issues.

Has anyone looked into to taking the Titan 43 gallon tank and using it for a gas-powered truck. Is this possible and how much modification would be needed?

Fuel stops are part of owning a vehicle, what's the problem?

Open highway Pepper gets about 25 mpg so one fuel stop between De Kalb Illinois and Denver. A forty gallon tank gets me there on zero. LOL. I stop for the day in Lincoln and stop several times a day. Often at a station. So...... My butt gives out before the tank does.

I’m always measuring time on trips. My odyssey will make the destinations these days without filling up. My trips are 6-7 hours mostly interstate driving. Rest stops are way quicker at rest areas than any gas stops. Saving me about an half an hour total. It makes a difference.

When towing a tall trailer on the interstate, I get 8-10mpg; for a stock range of ~184 miles max. I find this unacceptable, especially driving across the great plains at night. Looking for gas every 130 miles isn't a good feeling (or probably less, where is the next town with an all-night station that isn't 20 miles off the highway?) .

 

I don't put many miles on my truck; but when I do, it is often the above scenario. Having double the range makes my travel less stressful: I buy gas when I need a break, not every gas station.

 

It's not for everyone; but I love my 50 gallon tank!

I had a 100 gallon tank. I tapped into the return with an old fashioned manual switch by the driver seat. It was awhile ago I don’t know if you could do it on new trucks. I also had a fuel pump on the tank.

I'm sure it can be done. I need the space in the bed for other things.

I had an L tank with a tool box on top. Even an air compressor behind it. They were in front of my gooseneck ball. All that was in front of my fender well. Plenty of additional room in the bed.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
