Procedure Using Fuel Manual Shutoff Valve
- Rotate handle on fuel manual shutoff valve to CLOSED position. Fuel manual shutoff valve is located near driver's side rear tire, underneath the vehicle, near fuel lines just below fuel tank behind the rear seat. See Fig 1.
- Start engine and allow engine to idle until engine stalls. Ensure fuel gauge indicates EMPTY. If fuel gauge does not indicate EMPTY, restart engine and allow engine to idle again until engine stalls. If engine will not start, crank engine for a few seconds to release any residual fuel pressure. Turn ignition off. Wait at least 5 seconds after turning ignition off and then disconnect negative battery cable. Fuel pressure should be released from the fuel lines and fuel system components may be serviced.
