Fuel pressure settings change on me!!!???

[adam355]

Okay heres the deal. I will set the afpr to 43 psi with the vac hose off. 15 minutes of driving later it will drop much lower. One time it dropped down to 20 psi. I can kinda adjust it back or I can wiggle the connection that is around my gauge sensor and my fuel filter and it will change again. I know its not just the sensor giving me off readings because the car will starve of fuel when the pressure drops on me. The other thing i was thinking is that its next to my fuel filter that it could be clogged since its that connection I am wiggling. I just don't wanna go through the pain of changing the filter if thats not the problem. What do you guys think? Thanks

if you believe it's possibly the filter, change the filter. My bfp fluctuates sometimes, and it's an aeromotive w/ a liquid filled gauge. It moves 3-4psi at times.

My guess that its the filter is just an uneducated guess. I know nothing of what a clogged fuel filter can do to a car and it's fuel system.
