My fuel pressure gauge reads weird. I cant get it to adjust to 43 it goes to about 30 then if i tighten down the screw it goes to 0 and i can feel it surge with the engine idle. The pressure regulator will jerk with the surging pressure. Any ideas? is this cheap fpr just broke or what.?
 
Ok well since the gauge is on the crappy afpr, You can't trust it's reading, you need a real FP gauge. If you can't get it past 30 then it sounds like it's broken.
