Fuel System Pressure Release
WARNING:
Always relieve fuel pressure before disconnecting any fuel injection related component. DO NOT allow fuel to contact engine or electrical components.
- Remove fuel filler cap to release fuel tank pressure. Remove relief valve (Schrader valve) cap. Relief valve is located on fuel supply manifold. Using Fuel Pressure Gauge (T80L-9974-B), release fuel pressure from relief valve.
- If fuel pressure gauge is not available, disconnect electrical connector to Inertia Fuel Shutoff (IFS) switch. For IFS switch location, see INERTIA FUEL SHUTOFF SWITCH LOCATION table. Crank engine for 15 seconds to reduce system pressure. Turn ignition switch to OFF position. Reconnect IFS switch connector.
