quote Phil B:
Could it be a leaking pump diaphragm? Are the plugs the same color?
Ditto for me on this one. You can loosen the pump from the power head, put a couple of extra screws and nuts in the pump mounting holes to keep the pump from leaking externally, then pump the bulb hard and see if fuel comes out of the pump’s pulse hole. If it does, the diaphragm is no good.
Long live American manufacturing!
