Upgrade to a larger fuel tank

I have the same complaint. I found this site selling larger tank upgrades for our trucks as well as other years.

Mount your spare in the bed, and throw the 42 gal suburban tank in there.:tongue:

Since the tank mounts on the frame rail, there should be plenty of room to change the tank to a larger one. It's more than likely going to be a little larger, but mostly longer than your original. Shouldn't be too hard to do.

Wow, those are some pretty steep prices for replacement tanks

I for one am going to spend the extra money for a 52 gallon Titan fuel tank which is a direct replacement for the stock. Then I will use my EFI Live to reprogram the ECM for the increased capacity so my DIC displays accurately.

I own a 2006 Silverado 2500HD. It is the extended cab with 6.5 foot bed. It has the 26 gallon tank. I only get about 250 miles before I am down to the quarter-tank level. I would like to convert it to the GM 34 gallon tank. Is this possible? Is there room for a larger tank underneath the vehicle? How hard is it to do? how much does it cost? Anybody have any ideas?

I wanted the same thing for my '91 K1500 short bed, as I understand it, the bigger tank is for the long bed trucks. So that's when I stopped thinking about it. I figured it wouldn't fit because of the short bed. But I guess the million dollar question really is, what are the dimensions of the larger tank vs/ free space available. That is really the only limitation.

I bought a 08 Chevrolet one ton box truck and I want to put a bigger tank in it
