I have an AEM fuel rail and an aerom fpr. I curently have my fuel pressure gauge on the fuel rail. Should I move it to the fpr or leave it on the rail, or does it even matter? thanx for your guys time in advance.

 

If you have your FP gauge on the rail, doesn`t that make it hard to read at WOT? If it is on the rail then it is only good for reading pressure at idle with the hood popped open and the car parked at the curb. Or, am I missing something here?

You shouldn`t even need an adjustable FPR if you are running under 800 WHP. The stock FPR will do the job just fine in almost all except the craziest possible fuel delivery scenarios.
