i was wondering how to hook the fuel pump up to the truck stand alone system. the 5.3 is out of a 2002 chevy and has around 22k. i am using a 4l60 tranny with it.

Not sure, and shouldn't post. But some of these vary the voltage to regulate the pressure in the late engines. Anyone know on this model/year?
