return fuel line.

[ngarman123]

where should i run my return fuel line. i am putting in a by-pass regulator and was wondering where i should run the return line? is there an input on the sender that would accept return fuel or do i need to put a fitting in the top of the tank. thanks

What year & GVW your truck is will determine if the sending unit has a return port on it. If it doesn't, you could either replace it with one that does, install a fitting in your existing sending unit for one or install a fitting in the filler neck close to the tank at a downward angle. Lorne
