After a long work weekend and taking it easy yesterday, I tackled my EFI fuel tank. Following the easy to follow instructions, I measured, cut and assembled the fuel pump and return along with the fuel sending unit. Tank was 6 3/8" deep, mid point for the rheostat was 3 5/16". Everything checked out, fuel pump sits nicely in the built in reservoir. I used PTFE thread sealant on all the mounting screws. The tank mocked up easily. I used some peel and stick roofing seal as my anti squeak strips on the tank and straps. I plan on using a C5 filter/regulator when I run the fuel lines. Turns out the FiTech calls for 58 psi so that works out well.
