F150 (Fuel Tank Solenoid Valve Stuck Closed Or Inoperative)
WARNING: This page is about a different variant/trim than selected.
- Connect Grounding Cable (134-00121) to back side of the fuel fill valve at the fuel line connection. See Figure. Connect grounding cable to ground rod. Turn in the manual lockdown valve jackscrew on the fuel tank solenoid valve(s). See Figure. Connect Fuel Filler Neck Venting Kit (134-00117) to the fuel filler valve. See Figure. Connect Venting Hose (134-00118) to the fuel filler neck venting kit. Connect the venting hose assembly to an approved vent stack.
- Remove fuel tank solenoid manual lockdown valve. Install Manual Override Tool (134-00050) into fuel tank solenoid of the tank being vented. Turn manual override tool jackscrew inward until fuel begins venting. Slowly open manual backflow valve on fuel filler valve and observe gauge pressure of filler neck venting kit. Pressure reading should be tank pressure.
- Slowly open bleed valve on the fuel filler neck venting kit slowly and allow contents of fuel tank to vent through vent stack. Venting LPG fuel tank may take more than an hour. Vent the fuel tank until the fuel flow through vent stack stops. Close the manual backflow valve on fuel filler valve when LPG tank contents have been vented. Perform LPG FUEL SYSTEM PRESSURE RELEASE (FUEL LINE VENTING) procedure.
- Remove manual override tool from LPG fuel tank solenoid valve. Install fuel tank solenoid manual lockdown valve. Turn manual lockdown valve jackscrew inward on fuel tank solenoid valve. Repeat this procedure until all affected tanks are vented.
WARNING:
Ensure the jackscrew in the manual override tool is backed out fully (counterclockwise) before installing into fuel tank solenoid valve. Installation of manual override tool in the venting position will cause natural gas to be released immediately.
