Will not stay running

Hi,

Glad to hear you got it running. The o-ring makes sense based on what you were getting at the engine, foam.

As far as the new issues, confirm fuel pressure is within spec. If you need us, please start a new thread specific to the issues. We try to keep the threads specific to one topic so they are more likely to help others. I hope you understand.

My guess would be that the o-ring had a small amount of damage and with the way those lines attach the fuel flowing in the line through the connector was acting like a venturi when the pump was on and that pulled in the air. Then when the pump shut off the air acted to limit the fuel pressure and the ring pushed back enough to seal so there were no leaks. Not a common failure but it happens.
