All of you helpful eyes and fingers...

Right now I have a pressure gauge connected where the Schrader valve goes (before the fuel regulator) so it couldn't be a fuel regulator problem because the pressure reading is before the regulator.

The only thing I can think of is an Obstructed fuel line because I already changed the fuel pump, fuel filter and fuel return valve in the sender and the fuel pressure still drops from 55psi down to 10psi.

Will like to know from you experts out there if there's an element in the Engine system that may signal the ECU or the fuel pump to drop pressure.

Please Help... desperately...

Thanks a Zillion!
