Repair & Maintenance 2006 rancher won’t stop leaking fuel October 9, 2015 I just put a new petcock and carburetor. I drained the gas and cleaned out the tank. Gas is pouring out of the overflow tube. The only time it stops is when I turn the flow off on the petcock. What in the hell else could this be from?
