Fuel System Pressure Release

WARNING: This page is about a different car, the 2003 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Always relieve fuel pressure before disconnecting any fuel injection related component. DO NOT allow fuel to contact engine or electrical components. Always refer to safety procedures to reduce possibility of injury. Before performing any fuel system related procedure, read and follow fuel system safety precautions. See FUEL SYSTEM SAFETY PRECAUTIONS .

Remove fuel filler cap to release fuel tank pressure. Remove engine appearance cover. 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. This will drain some fuel out of fuel system.
