Larger gas tank for LWB pickup

[stevenk20]

hello everyone i did a lot of searching and didn't really find what i needed. i am doing an EFI swap and i wanted to get rid of my two side tanks in favor of a single large tank i will mount behind the rear axle. i'm looking for around 35+ gallons as this truck will be used for towing in the future. can i see your gas tank swaps in all you first gens?? also it would have to have a 0-90 ohm sending unit.

i really don't mind relocating crossmembers or anything like that so anything is fair game. this truck will not be wheeling so ground clearance is not a huge issue either, i dont want it to look stupid low though :-) thanks everyone
