Im not getting any power to my fuel pumps on my 91 f150 5.8L, ive traced the power coming into the tank selector switch but cannot find any power on the other side of it. is there a way to bypass the switch since i only use the rear tank anyway? just priced a new switch and its out of my budget right now.

 

I'm not too familiar with that component but I did bypass my switch. I did not plumb the fuel lines to the unused tank though and it seemed to move the fuel betweent the two and eventually started leaking fuel again.

I eventually plumbed the unused tank out of the loop and all seems ok now. (well abandoned the switch completely and just use the one tank).

 

the lines to my front tank were crimped off when i got the truck. tried bypassing the switch but nothing. will update if i get it figured out

 

If i have power at the tank selector switch but not at the pump and i have bypassed the switch, cant i just run a new wire to the fuel pump to eliminate any bad connections/broken wires in between there? theres nothing else on the (very bad) schematic i have. just making sure before i replace the wire altogether.
