air bubbles in fuel line

[Charles Johnson]

got a 1985 j10rcom johnson 9.9 when running at greater than half throttle i get air bubbles in the clear fuel line running from the pump to the carb bowl.

just ordered up a new fuel pump assembly since mine wasnt so good looking anything else it could be?

About the only thing that goes wrong with the pump is a diaphragm, available at $3.99

check fuel line fittings. I had same problem few years back.Thought was pump.
