just installed a ispro fuel pressure gauge what are the readings i should be seeing at idle and when accellarating ? and what are the readings or symptons i should see on the gauge when filter needs a change or lift pump issues thx ahead of time aloha Hop Sing

 

Should be 22 psi at idle, about 25-30 @ 2500 RPM. Pressure will start lowering when you need a filter change.

 

thx daveO thats were i am at!
