Go to a swap meet, and find an original style fuel pump that's held together with screws.

Buy it- - - -as long as the housing isn't cracked or badly corroded, it doesn't matter if it works.

Send it to Then and Now rebuilders. It will come back with an ethanol-resistant diaphragm, good inlet and outlet check valves, and the right pressure.

Stop worrying about excessive fuel pressure.
