AFR Problem (maybe Fuel Pump installation bad)

So my fuel pump went bad, it was making a wierd sound while driving and also my AFR was Mid 14 at WOT.

i replaced the pump it self, didnt touch wires at all.

after putting everything back together car started right up and AFR was arounf 11.5

after a couple hours car started stalling and AFR went up to 13-14 AFR

what could i have done wrong in the fuel pump installation?

thx

What FP you installed? Depending on which one you installed the installation method changes.

You need to put 3 O rings and no white spacer on the top nipple to make it close like stock and hold pressure.

White spacer and one O ring should work too. Someone xjohnx posted the other day the O ring Napa part number. Look at his recent posts.

If you have white spacer and two O rings, I have to assume your FP canister does not close as stock with the white pins and needed to be close via the wraps or similar correct?

If so, I would remove one O rings and make it close like stock with the white pins.
