Fuel in vacuum line

[rks]

Yes it will. The diapharms do go south after a while, on both petcocks and pumps. I replaced my pump earlier this year when I noticed the inside of the vac line was wet. Scooter ran fine, but, when restarting a warm engine, like after a 15 minute coffee stop, just a little bit of throttle was needed. Thinking I needed a new auto enricher, I started poking around and found the wet vac line.
