Can't talk you into a rear mounted fuel tank? (ye$, i know... more co$t)
The boyd 67-72 rear tank does fit into our 66's. Rear sumped fuel tank w/ an in-tank Aeromotive Stealth 340. Price isn't 'too' bad either.
in tank pump... that is outside of the cab.... I'm hoping with a full tank of fuel I'll barely hear it at start-up.
