1991 Ford Escort dirty fuel problem

Engine Mechanical problem
1991 Ford Escort 4 cyl Two Wheel Drive Automatic

For reasons I wont go into here, I had to offload fuel from an RV that had been sitting around for a year or more. I siphoned it off a gallon at a time into a gas can, and used a funnel to put in into the Ford, and before I knew it had overfilled the latter. I suspect there was either rust or water, because it sputtered when I tried to start it, and soon stalled.

1) The check engine light came on which I understand due to the over filling – can I make it go away by disconnecting the battery?

2) Can I disconnect the gas line at the engine, run the pump to clear the line? If so, where do I disconnect it. If not, what do you recommend?


Thanks GH.
