1st thing is to shut off the valve inside the car, under the tank on passenger side. In the "off" position, that valve handle will be pointing towards the passenger door. Get a can, not glass jar, to catch the fuel that will come from the filter bowl. Make sure there is NO smoking, or ignition sources near you. Gas and gas fumes are very dangerous. Loosen the round finger nut that holds the glass bowl to the filter housing.Swing the wire form away from the bottom of the bowl while holding onto the glass! Hold the can under it and remove the glass. It will be full, and spill a bit into can, especially if it is a bit stuck. The cork gasket may stay up in the filter housing OK. If someone used a gasket sealer in the past, the gasket may rip and come off in pieces. You'll need a new cork gasket. Empty bowl contents in can. Cover it or put the gas in a safe place when done. Take a rag and wipe out the glass bowl, Put it back together in same order you removed it. Tighten the bowl nut nice and tight with your fingers only. Don't use pliers. Turn on your gas valve in car and check for leaks.
