Fuel pressure help.

[jubelands]

My fuel pressure is bouncing 5 - 8 psi constantly and was wondering if this is normal or happening to anyone else.

I've made many posts about chasing down the problem but despite all the help i've gotten and everything i've tried it wont stay still.

So i just wanted to know if it is happening or happened to anyone else. Changed fuel filter, fuel pumps, fuel relay, fuel pump resistor, fuel regulator, even added a DC fuel controller, bouncing is still there.

Happened to me once before but went away. It came back after i installed my KB and 60lb injectors but now nothing i do will make it stop bouncing. Help.

Have you tried another guage?

Oh yeah i forgot I did also try another gauge.

Same brand gauge? Changed the sending unit too? Oil filled or digital might be the answer. Another question, where is your sending unit mounted?

Its actually a mechanical gauge, goes straight to the fuel rail. It's an autometer btw.
