My manual for that/my engine shows the pump output pressure:
WOT: Min-Max 3-10 with 8-10 PSI normal.
Idle: Normal 2-3 with 1 being minimum.
Fuel pump suction measured with a vacuum gauge Teed into the fuel delivery line to the engine is 2.5" Vacuum increasing slightly with RPM increase....more vac.
It also says that the pump is designed to lift 5' with a 5/16 fuel line but connectors and other things along the way can reduce that distance......5' vertical lift is a lot more than I thought it's capability.
