Originally posted by tlowe I.I.#1716: i did find a problem though. in the shop i triggered the fuel pump relay and measured the voltage to the pump at the pump. it was 10.7 @ 55 psi. so i changed all the wiring to a larger guage and retested. had 11.8 with no motor running and 12.5 @ battery.tom
Just curious, you are running a relay to power the pump? What gauge wire did you move up to? Most of a volt drop still sound high to me (but then I tend to use wire that is WAY bigger than is actually necessary).
