gas smell and weird mileage 97

Postby RBGERSON » Wed Aug 08, 2012 6:16 am



If my petcock assembly is leaking where does it leak to?? the gas tray is dry and no gas on the floor?? Sometimes I get a big gas smell after she is parked and my gas mileage varies too much from 38/42 to 30/33 under dame driving conditions..figure it leaking some how...petcock my first thought. But I don't want to rebuild until I know that's it for sure..so if it's leaking where do I have to look for evidence...

It can only leak into the tray. The tray drains out onto the ground. Gas evaporates quickly so you might not be able to see it. That much variation in mileage should show up in the tray if that is what it is. Do a vacuum leak test on the valve to test it. It should indefinitely hold vacuum. No leak down.
