Fuel System Pressure Release (Fuel Line Venting)
WARNING: This page is about a different variant/trim than selected.
WARNING:
Always release (vent) fuel pressure before disconnecting any fuel injection-related component downstream of fuel tank shut-off solenoids. DO NOT vent fuel system indoors. Manufacturer recommends venting fuel through a vent stack.
NOTE:
To perform fuel system pressure release, Fuel Rail Test & Venting Kit (134-00116), Grounding Cable (134-00121) and Venting Hose (134-00118). Manufacturer recommends venting fuel through a vent stack.
- Insert grounding spike into earth. Connect Grounding Cable (134-00121) between grounding spike and fuel injection supply manifold. See Fig 1 .
- Turn manual lockdown valve jackscrew on each fuel tank solenoid valve. See Fig 2 . Connect Fuel Pressure Test & Venting Kit Hose (134-00121) to Schrader valve on fuel rail. Ensure valve on tester is closed. Connect Venting Hose (134-00118) to Fuel Pressure Test And Venting Kit (134-00121) manifold.
- Remove fuel pump relay from power distribution box. Construct a jumper wire approximately 6" long with spade terminals on each end. Jump fuel pump relay terminals. See Fig 3 or Fig 4 .
- Slowly open bleed valve on fuel pressure vent and test kit manifold and allow fuel to vent to atmosphere for one minute. Close bleed valve and remove pressure test and venting kit from vehicle.
