- Remove fuel cap to release fuel tank pressure. Remove relief valve service port cap. Relief valve service port is located on fuel supply manifold. Using Fuel Pressure Gauge (T80L-9974-B ), release fuel pressure from Schrader 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 with IFS disconnected for 15 seconds to reduce system pressure.
