[QUOTE="MG0h3, post: 15450847, member: 164690"] Just got done doing this and I used a couple 40amp relays rather than the FORE one. Couple notes if you go this route and are using a HOBBS to fire the second pump: Since youll be using pin 10 (originally fuel pump power) to power the relay, open up the harness about 6" downstream from the FPDM and youll find a nice factory junction where it splits into two wires to feed both pumps. This is handy as an easy way to have both relays powered from KEY ON power. I went this route because I wanted to have the HOBBS controlling a ground, mainly for ease but also to limit extra hot wires running back to the truck. A quick and easy way to have the pump run full time for whatever reason (leak checks or fuel pressure adj.) is to unplug the hobbs and insert a mini fuse in the plug. [/QUOTE]
