Tek74 Posted January 4, 2016 Share Posted January 4, 2016 I'm good with my smaller fuel tank, as don't tow much at this time, and I have a 5 gallon gas can I can bring with me for long hauls. However, I still like the old-school idea of a truck having the room to allow the owner to install a 2nd fuel tank. Hopefully GM builds all the Max Tow trucks with larger fuel tanks.

Rock1500 Posted January 4, 2016 Share Posted January 4, 2016 I really wished we had the option for larger gas tanks. It would be nice Sent from my SM-N900V using Tapatalk Link to comment Share on other sites More sharing options...
redwngr Posted January 4, 2016 Share Posted January 4, 2016 Most I've put in is 24.6 gallons.

So far, max tow has the same 26 gallon.. Link to comment Share on other sites More sharing options...
redwngr Posted January 4, 2016 Share Posted January 4, 2016 I just filled up from empty, 22 gallons. Why is that? Not the 26 gallons I thought I had. 2016 1500 double cab standard bed. Did you run it dry and it still took 22? If so, the fuel pickup must be higher in the tank than it's supposed to be. Link to comment Share on other sites More sharing options...
shockedimpy Posted January 4, 2016 Share Posted January 4, 2016 It said I had about 51 miles left. The fuel indicator came on right when I filled it up. Link to comment Share on other sites More sharing options...
DougIrby Posted January 4, 2016 Share Posted January 4, 2016 A larger fuel tank would be a nice option. However, once you get old your bladder needs emptying more often than your truck requires a fill up, especially when the wife is with me. Link to comment Share on other sites More sharing options...

Chevyguy85 Posted January 4, 2016 Share Posted January 4, 2016 Could be worse my 73 had a 20 gallon tank and we used to tow a 31' Airstream with it. 350 4 barrel carb through the lower Appalachians. Our 2500s and 2500hds had the 26 gallon. It sucks but we were stopping every hour to two hours for grandma's bladder anyway so we made it work. Good to know the HDs got the bigger tank regardless of bed size. Link to comment Share on other sites More sharing options...
diyer2 Posted January 4, 2016 Share Posted January 4, 2016 I agree with jraschke11, the fuel does cool the pump so I have never run the tank low. The last time I put in a fuel pump was on my 93 Silverado, the dealer parts counter people were surprised how many miles I had on the original fuel pump(I don't remember the miles). The head service tech was within ear shot and made the comment "you don't run your tank low on fuel do you?" Fuel cools the pump but more important IMO it lubricates it keeping the temps down that equates to less wear. That fuel pump in my 93 is still going with 243k miles on the truck.

lsxrx7 Posted January 4, 2016 Share Posted January 4, 2016 is there enough room to upgrade our stock fuel tank from the 2500 HD ? Link to comment Share on other sites More sharing options...
Georgia1911 Posted January 4, 2016 Share Posted January 4, 2016 Did you run it dry and it still took 22? If so, the fuel pickup must be higher in the tank than it's supposed to be. It said I had about 51 miles left. The fuel indicator came on right when I filled it up. 51 miles is about 3 gallons so 22 makes sense. Most fuel indicators I have seen trip at about 50 miles. In addition to the fuel pump lube/cooling issues, running any fuel injection system dry is a problem, but even more so for a high pressure DI one.

EEEliminator Posted January 4, 2016 Share Posted January 4, 2016 Is there any reason the 36 gallon tank won't bolt in? Link to comment Share on other sites More sharing options...
moosehead1 Posted January 4, 2016 Share Posted January 4, 2016 +5 to towing with a larger tank despite my massive prostrate. Link to comment Share on other sites More sharing options...
Omar1 Posted January 5, 2016 Share Posted January 5, 2016 +1 on tundra it has 38 gallon fuel tank. If GM 5.3L engine had 38 gallons, the fuel range would be over 700 miles Link to comment Share on other sites More sharing options...
