Fuel problem

[jeffmo]

Over the last several years while I've been out on Erie I had a problem w/ the motor shutting down and it's driving me nuts trying to figure it out. It has to be a fuel delivery problem and my guess is that it's in the line from the tank to the motor. I'll be running and it'll shut off like I've turned the key off. The fuel bulb will be collapsed and all I have to do is remove the line from the tank side of the bulb, allot it to fill again and then re-attach it. Then the motor runs fine. This has happened maybe 3 time in as many years. The vent is open and clear so I'm guessing that isn't the problem. I had heard that I need to replace the fuel line from the tank to the motor fuel line to correct it.
Any suggestions would surely be appreciated and thanks ahead of time!
