Update:
Went driving about 2 hours later. LPFP & HPFP were both sitting at 64psi before startup, upon startup lpfp went up to 83 but then shot back down to ~62psi seconds later. HPFP seemed fine at about 700+ psi at idle after startup. HPFP reaches 2500psi on cold start, and progressively less and less the warmer the motor is. LPFP is running consistently in the low 60 psi range though.
After shutting off both lpfp and hpfp stabilize to 76psi.
It seems like my LPFP is starting to let go actually, but how long will the fuel regulator keep the pressures at what they should be in the 70psi range? Should I be concerned about that as well I'm not 100%. Anyone think it could be something else going on besides LPFP letting go?
