Description

I need a fuel pump replaced in a 1983 Toyota rv. Might need the backflow valve replaced as well. It's a v6 efi 3.0 from a 1989 Toyota rv I swapped into it. Based on my understanding you either have to cut a hole in the floor or drop the fuel tank. I would prefer the latter. I confirmed that the part is available in the auto parts store.
