After it sits for a few hours, I think the fuel is draining out of the fuel rail and pump, so I have to manually prime it to get it going again. There is a clear in -line fuel bowl right next to the pump/primer, and there was only a little fuel in the bottom/lower end of it (the end away from the pump& engine). I checked the fittings on the fuel filter, the seal on the hoses, clamps on the fuel bowl, etc. but cannot see anywhere it might be sucking air...so I think the fuel is just draining back into (or towards) the fuel tank. Do I have to replace the whole pump, or is there some o-ring seal or check-valve that I can replace to fix this?
