OK, can anyone tell me where the 3 lines from the fuel pump go to? I am installing a electric fuel pump and need to know what goes where. PO had one on it, It went out so I took the old one off and forgot how the plumbing went. dumb ass, I know.
thanks

sorry, meant 2 lines for the fuel pump. I think the solid line on the bottom of the frame rail feeds the pump and goes to the banjo fitting and the other goes to the return line? if this sounds right please let me know.
thanks

I am not sure on a 75, but on the later model pump, their are 3 lines at the pump. One inlet, one return, and one outlet (to carb)

2 lines, simple

blow or shoot air down the lines, the one that bubbles in the tank is the feed, then the other is return,

if both bubble you have a full tank and or vehicle is leaning to much
