Specs are in for psi testing. Here's what i have.

Engine running- 58 psi
Key on and engine off- 52 psi
after 12 min- 48 psi
after 21 min- 40 psi
after 31 min- 32 psi

Do these numbers look normal? The pressure does drop (looks like 8 psi every 10 mins) and i'm guessing eventually to zero but i stopped after 31 mins. I am also noticing gurgling sound in fuel tank after putting this pump in. Does not sound normal. WTH!!!

    In response to kmdakota1

If those are engine off with key on (KOEO)
Then I would say that is good.
As long as it is good while it is running.
It will drop with KOEO as the pump only runs once for a few seconds to prime.
It runs continously while running
