Question lift pump woes

Put in a new lift pump (fuel transfer pump) and I still can't hear the @#$%^ thing as I think I'm supposed to. Also have an LED (to tell me when it fails) to wire to it but don't have the wiring diagram for it

No less than 7 psi @ WOT...(assuming you're driving a 24V / VP44 equipped vehicle)

Pleas fill in your signature so we can see at a glance what you're driving.....makes it easier to answer any questions

Put in a pressure gauge. An inexpensive mechanical one can be bought for $7 from the Surplus Center and installed without an isolator onto the middle 1/8" NPT fitting on the top of your fuel filter housing.
