Ok here is the situation. This motor is on a tracker pontoon boat. I am going on my yearly trip on Saturday and I checked out the boat this weekend and here is the problem. I have 2 external gas tanks and no matter which tank I am hooked to when I squeeze the bulb is does not get hard and it does not pump fuel. The error is in the correct direction. When I would squeeze the line disconnected from the motor but hooked to the tank the fitting that plugs into the motor had an air leak around the ball. I replaced it and still the bulb will not get hard and when you squeeze it will not siphon anything out of the tank. I then removed the fitting on the tank end and stuck the fule line directly in the tank and the bulb get hard and the engine runs fine. So my question is do I have a bad fuel line/bulb? or tank pickup. I have a hard time believing that both tanks have a fuel pickup problem. They were working fine last year when I parked the boat. The only thing I did not replace was the fitting from the fuel line that plugs into the tank but it was replaced last year. Is there anything else I am missing. I have already ordered a new fuel line with ends but want to make sure I am not missing something obvious. Any help will be greatly appericated. Thanks.
