I have a 2019 sdx 270 with a verado 300 OB. I recently had the boat detailed. It ran for about 10 mins then bogged down and stopped after that. The guy who sold it to me had warned me to avoid washing the fuel vent outlet. I don't know if this happened. I pulled the vent off and the screen is clean. The engine runs perfectly from an external fuel tank. There is no inline fuel-water separator. There is a squeeze bulb that is dry in the original line. I replaced it. Still won't prime. I siphoned fuel up to the bulb but it won't stay primed. I checked the hose clamps for air leaks and checked the lines for cracks. Is there some vent line filter that could have been clogged by water, etc? I checked the fuel I siphoned and it is clean. Basically, the neither the engine nor a bulb will pull fuel from the tank. I tried leaving the fill cap open but that didn't help either. Thank you
