Wasn't sure which forum to put this in so feel free to move...
I have a 1954 Chevy 3600, moved the fuel tank out of the cab about 5 years ago. Current setup is a custom made 35 gallon tank located in the bed.
This has worked great for years but times have changed and id like to relocate to an underbed tank and reclaim my full bed space.
The problem I'm finding is that most aftermarket tanks or those from the normal donor vehicles (Blazer, mustang, el camino, 47/48 suburban) do not appear to fit or work with my 3600 frame. Most are geared to the more popular 1/2 tons.
I seem to have the width (side to side) but not the length (front of truck to back) due mostly to the extra crossmember on the frame. Depth of tank also is flexible though ideally somewhere between 10-12" as id rather not have the tank super low.
I don't really want to move the crossmember or pay $500+ for a new/custom tank etc. unless i absolutely have to. Location isn't as big of a deal, weather its behind the cab on the side of the frame rail or behind the rear axle. The space between the last crossmember and the rear of the frame is roughly 17x31.
FWIW the truck will soon have a flatbed which should allow me some added flexibility.
Ive gone thru multiple searches on this site and others with no luck... curious if anyone knows of a tank roughly 17x31x 10/12" deep. Or anything else that might work. Bigger volume the better.
Thanks in advance
