I have a 1970 C10 350 V8 fleetside shortbed. Can anyone tell me if there will be any problems arising if i were to relocate my gas tank to the top of the bed? Can i just be able to extend my fuel line and electrical wiring and connect it to the sending unit without running into any more problems? I need some advice on this before starting this project. Will i be messing with pressure or having to replace the fuel pump?
