Need more fuel capacity... Only problem I have is the very small gallon size tank. Why do they install a tank of this size?
Any ideas where amd who sells and installs extra fuel tanks?

You cancer a teansfer tank for in the bed but they are illegal a lot of places or you can get a Titan fuel tank they hold from 43 to 52 gallons

Transfer-Flow. I have a 2007.5 LMM and I replaced my stock tank with their 45 gallon tank. Excellent company with a great product. Best option I have ever added to my truck. Since I haul a fifth wheel 6 to 8 times a year I don't have to stop so often to get fuel.

What is an approx cost for this? Does a GM delaer have to remove and install it?

Titan fuel tanks is who I would look to. I can get you a price if you can get me your zip code for shipping purposes! I have sold several of these units and everyone who has them loves them. They will get you in at the 52 gallong capacity. Let me know if I can help you out!

I have a 2008 2500 HD Chevrolet 4 door LTZ

I would be interested too... Same truck as stated above... 99208 zip, thanks!

I have a RDS 51 gallong fuel tank /tool box combo in the bed of my truck that gravity feeds into the stock tank. Made my own adapter and spliced into the fuel fill with no check valve. I can leave the valve open and no leaks. The fuel gauge in cab does go to E after about 80 miles of the fuel gauge not moving but once the level starts dropping in the factory tank it reads right again.

My 34 (long bed) tank works well for me - but notice GM put 36 gal tanks in ALL pickup models starting with 2011 models. There's always something better in the new model.

i bought a 55 gallon transfer flow tool box/fuel tank combo to fix that problem. them went to northern tool and bought their gravity feed system to use the filler neck adapter with. wired up a switch and relay and can fill up on demand while running down the road. fuel gauge works properly also

check craigslist for a used tank. sometimes its worth it to get one that looks rough then have it blasted and bed lined or power coated.

i figure i have about 70 usable gallons and it makes it very nice

i bought a 60 gal tank tool box combo off of craigslist have a small pump to the fill kit from northern tool all works great, no leaks. anyone hear if we can but the factory tank from a 2011 on our trucks?

I would like a Titan Tank if they could figure out how to make the factory gauge work with it.
