On my Eska 15hp (Tecumseh powerhead), my fuel fitting leaks fuel (female end) when I disconnect from my motor. I can hear a hissing sound when I hold fitting higher than the tank (fuel being pulled by gravity back down into tank)? Primer bulb is mushy. I think o rings are sucking in air while running and giving me trouble. Plunger inside of fitting is free. What other symptoms would this leak give my motor? Fitting looks like an quick disconnect air fitting. Thanks.
