Re: Fuel Pump Pressure??

The lack of suction in the first place sure sounds more like a pump valve issue since the diaphragm is OK but the drop off after running could easily be a delivery/supply issue.

Any chance something is restricting the flow such as debris in tank or the screen inlet filter in pump? The flex hose liner has been known to collapse under suction when more fuel is called for & several have reported problems with the tank vent.
