Fuel Pressure Release & Fuel Line Connections
WARNING:
Fuel system is under pressure. Release pressure before servicing fuel system components.
- Remove air cleaner assembly. Remove fuel cap to release fuel tank pressure. Using EFI Pressure Gauge (T80L-9974-B), release fuel pressure from pressure relief valve on fuel rail. Before disconnecting fuel lines, disconnect negative battery cable.
- 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. 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 lock 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.
