About LinkBacks1972 Johnson 50 hp...was fishing saturday, headed back to the ramp and motor started bogging down and then quit. looked at the fuel line back there and noticed the fuel bulb coming out of tank was completely sucked in? Never seen that before. I disconnected line from tank an motor and then poked the little ball inside one of the connectors and the ball relaxed...it did it one more time on me after we went to a different lake for some more fishing. What is causing this?

Re: Fuel tank bulb caving in?
Is the tank vent open?
Sent using a tin can and a piece of string. A technological breakthrough. The tin can is a 1966 Starcraft Nassau powered by a 1966 Merc 500.

Re: Fuel tank bulb caving in?
Your fuel tank is not venting properly.
I love the smell of a two stroke early in the morning
Currently running a 1971 Starcraft JetStar powered by an E35QLEDC and a 4436R

Look for a restriction on the pickup tube in the tank itself.
