how does the fuel pressure regulator come off the fuel rail on a 1997 chevy vortec 7.4 MFI engine? We have the fuel rail out and the vacuum activated fuel pressure regulator appears to be attached directly to the fuel rail. There is not the normal clip holding it on that you would see on non-MFI engines (TBI). Its either pressed on, or somehow attached to the bracket which is attached to the rail.
