Fuel Pressure will not stay where I set it. Please help.

I will set the pressure to 43 psi vac hose off. A little bit later it will either jump higher or drop way lower. I bought a new fuel filter and it made no difference. Has my walbro gone bad, do I have a leak, my afpr break? I can't seem to find the problem. Anyone got any ideas? Thanks

What gauge are you using and do you have it mounted in the engine bay?

 

[adam355]

I have a Nordskog gauge and sensor, the sensor is mounted next the the fuel filter and the gauge is in the car.

maybe a bad electrical connection... just a guess; has it been rewired?
