Fuel in vacuum line

I'm guessing this is an indication of a bad petcock? The vacuum line has fuel flowing thru it freely, think that'll throw the mix off?

going to the hardware store to be a shut off tomorrow

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.
