Fuel System Pressure Release
WARNING:
ALWAYS relieve fuel pressure before disconnecting any component under fuel pressure. DO NOT allow fuel to contact engine or electrical components.
- Remove fuel tank cap. Using Fuel Pressure Gauge (T80L-9974-B), release pressure from system at pressure relief valve (Schrader valve) located on fuel injection manifold rail.
- If fuel pressure gauge is not available, disconnect Inertia Fuel Shutoff (IFS) switch. IFS switch is located behind right side of instrument panel. Remove fuel filler cap to release fuel tank pressure. Crank engine for 15 seconds to release system pressure.
