what should the pressure be on a new lift pump from NAPA. i have 13. 5 to 14 at idle.

Allowing for gauge variations, yours sounds fine - once it loosens up from wear-in of motor brushes and pump vanes, it may increase slightly.

Sounds good. I've been running 15 at idle and 10 WOT. Jus curious which gauge u running, elec/man ?

I just replaced my pump this morning before work. I am seeing 16psi @ idle and 10 @ WOT. This is with a Westach electrical gauge.
