Redtop SR Fuel Pressure Issues - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have an AEM 340 fuel pump and have the following questions:

I tried the nismo fpr and found that it pulses the fuel pressure instead of having a smooth flow of fuel as soon as I adjust it to over 40 psi. Is that normal? I decided to run the stock FPR just in case.

Is it normal for fuel pressure to drop as soon as I turn off the car? Especially with the AEM fuel pump. Does it like backflow and then relieve the pressure once it's off, somehow?

Thanks.
