jimberg,

I've experienced the same thing. The stock regulator held pressure (until the fuel pump died...replaced the fuel pump and it still held pressure). When I put on a BBK AFPR, the pressure dropped right away when the car shut off. However, I also put on a set of FRPP injectors at the same time (tried a set of nearly new 30's...bad idea, and currently have a set of new 24's). Maybe the injectors dump the fuel??

I assumed it was normal. If it truly isn't normal, I'd sure appreciate an idea of what would cause it. It's not the lines or the pump since it held pressure with the stock regulator.
