Engine/Transmission (1998.5 - 2002) ISSpro F/P gauge ?

[RKraft]

I have a question about my Isspro fuel pressure gauge. It is a 30psi mechanical gauge with isolator, I installed my gauges and Edge box yesterday. Any way the gauge reads 20psi when key is turned on and when running but then it pegs out to 30psi then once in a while it will go back to 20psi. Running do the road it reads 20psi cruising and 15 at WOT. Any suggestions, I tried bleeding the gauge again.



Thanks
