Fuel Pressure Release

WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect negative battery cable. Slowly open fuel cap to release fuel tank pressure. Remove protective cap from pressure test service port on fuel rail. Fuel service port is located at front of engine.
CAUTION: To minimize fuel spillage, wrap a shop towel around and under pressure test port.
Use Fuel Pressure Gauge/Hose (C-4799) with gauge removed. Place gauge end of hose placed into approved gasoline container. To release pressure, screw other end of hose onto pressure test port. After pressure is released, remove hose from test port and continue fuel system service. When servicing is completed, install protective cap on fuel rail test port.

WARNING: Before disconnecting any fuel line, or fuel system component during testing, repeat FUEL PRESSURE RELEASE procedure. Perform FUEL PUMP TEST with fuel tank at least half full.
