I have a fuel cell, magnaflow pump EFI 600, -10 lines to the rails and then the regulater (Aeromotive)-two dash 8's in then a -6 return. My question is as soon as I turn the key the pump primes the system to 48psi but as soon as the pump shuts off, the system falls to 0psi in a matter of 3 to 4 seconds. Is this normal for this pump/system? Should it hold Pressure?
My last system was two cartech pumps and a stock fuel tank, this system held pressure for several minutes.
Thanks.
I have this same problem with my aeromotive A1000 regulator and I called aeromotive today amd they said its completly normal. I called ot send it back to have it rebuilt and they told me they do it when they are new and not to worry about it
Yeah, it's common. The A1000s do it all the time.
Well it holds a steady pressure when the car is running. I guess the pumps do not have a checkvalve in them to hold the pressure.
I dont think they do, my A1000 did the same thing!!
