Out on the boat on Saturday and port engine stopped running. Checked the ball and it was empty. Once I pumped it a couple of times engine ran great until engine ran out of fuel. Apparently, fuel was not cycling though ball valve or some filter was clogged. What could this be? Fuel water separator clogged or bad ball or ??? I can get someone to come out and fix it, but I have a feeling this is something very easy. Once it gets gas, it runs great. Starboard engine…runs perfect.
