I have a problem

Losing prime in fuel line. I just put a new gas tank in and last year I replaced the bulb and line. Could the bulb be bad already? It's the one that walmart caries. Probably a real cheapy. I don't see any hoes or crackes in line. Any Ideas?

Bad bulb or air leak at a hose connection come to mind.

Check all you r connection points for cracks or loose fittings. When you pump the ball does it get firm and remain that way? If not, you need a new ball or you have a bad spot between the ball and the motor.

If it does get hard and remains hard, check everything between the ball and tank. Also, check your gas cap on your tank as well as the air die to make sure nothing is loose or clogged.

If it is doing this after a run, is your engine trimmed level, leaving the motor trimmed up with a carbureted engine can cause the fuel to dump
