Fuel Pressure Release & Fuel Line Connections
WARNING: This page is about a different car, the 2001 Ford Pickup, 2001 Ford Econoline, 2000 Ford Pickup, and 2000 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Fuel system is under pressure. Release pressure before servicing fuel system components.
- Remove fuel cap to release fuel tank pressure. Remove relief valve cap. Relief valve (service port) is located on fuel supply manifold. Using Fuel Pressure Gauge (T80L-9974-B), release fuel pressure from relief valve (Schrader valve).
- If fuel pressure gauge is not available, disconnect electrical connector to Inertia Fuel Shutoff (IFS) switch. IFS switch is located behind passenger-side kick panel. Crank engine for 15 seconds to reduce system pressure.
- To disconnect fuel lines, remove retaining clip from fuel line coupling. Use Spring Lock Coupling Remover (D87L-9280-A) for 3/8" line and (D87L-9280-B) for 1/2" line. Install spring lock coupling remover on fuel line coupling so it enters cage opening. See Fig 1.
- Push spring lock coupling remover into cage opening to release female fitting from garter spring. Pull couplings apart. Remove spring lock coupling remover.
- When installing fuel lines, install NEW "O" rings on fuel lines. Use only specified fuel-resistant "O" rings (Brown). Before installing, lightly coat "O" rings with clean engine oil. Clean fittings, and replace garter spring (if necessary).
- Install female fitting to male fitting and push until garter spring snaps over flared end of female fitting. Ensure lines are locked together and garter spring is over flared end of female fitting. Install retaining clip. Ensure horseshoe portion of clip is over coupling. DO NOT install retaining clip over rubber fuel line.
NOTE:
Install Black retaining clip on fuel supply line and Gray clip on fuel return line.
