Fuel Pressure Release
WARNING: This page is about a different car, the 1995 Jeep Wrangler and 1994 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Fuel system is under constant pressure. This pressure must be released before disconnecting or servicing any fuel supply or return system component. Wear proper eye protection when releasing fuel system pressure.
Disconnect negative battery cable. Remove fuel filler cap. Remove cap from pressure test port on fuel rail. See Fig 1. Place shop towels around pressure test port to absorb spilled fuel. Press test port valve with a small screwdriver or punch wrapped in shop towels. Remove shop towels and dispose of properly. Install pressure test port cap.
CAUTION:
Always replace "O" rings, spacers and retainers whenever fuel system quick-connect fittings are disconnected. Ensure fuel connections are secure by verifying that only retainer tabs protrude from connectors, and by pulling on tubes to verify that they are secure.
