is there any way for me to check my fuel pressure without a autometer/greddy or the likes pressure gauge? i know on my dads bronco you can check it with a vaccum pump. just wondering if there is some way to do it on the CA.

Because this is an electric fuel pump, generally if it's moving fuel, the pressure should be fine. I was using my 230K mile fuel pump on my CA and I didn't have a bit of trouble with it. The weird thing about electric motors is that they don't really wear like the motor in a car does. They usually either work or they don't. There isn't much of a middle ground there.

i am not worried about the pump working or not. its working. i am driving the car. i have been for about 2 weeks. what i am worried about, is my walbro 255 over-powering my stock FPR. i am probably going to buy a nismo adjustable. i just want to be able to check/adjust it without spending $150-$200 on a gauge.
