2. Connect the Grounding Cable (134-00121) to the fuel fill line connection. See Fig. 11 . Connect the
grounding cable to the ground rod. Connect the Fuel Filler Neck Venting Kit (134-00117) to the Venting
Hose Assembly (134-00118) and adapter. See Fig. 12 . Connect the fuel venting kit to the fuel filler neck
venting kit. See Fig. 13 . Connect the venting hose assembly to the vent stack. See Fig. 14 .
3. Slowly open the instruction lockdown valve jackscrew on the fuel tank solenoid valve of the fuel tank to be
vented. Observe the gauge pressure of the fuel filler neck venting kit. The pressure should be at tank
pressure if the fuel tank solenoid valve was identified as "stuck open". Slowly open the bleed valve on the
venting kit and allow the contents of the fuel tank to vent to the atmosphere. Venting can take in excess of
one hour. Close the bleed valve on the venting kit, and observe the gauge pressure. The pressure should
be at or near 0 psi (0 kPa). Remove the fuel tank solenoid instruction lockdown valve.
4. Install the instruction override tool into the fuel tank solenoid of the tank to be vented. Turn in the override
tool jackscrew until fuel flows. Vent the fuel tank until the fuel flow stops. Remove the override tool
from the fuel tank solenoid valve. Install the fuel tank solenoid instruction lockdown valve. Turn in the
manual lockdown valve jackscrew on the fuel tank solenoid valve. Repeat the procedure until all affected
tanks are vented. Install the fuel fill line onto the fuel fill valve.
Solenoid Stuck Closed Or Does Not Operate
1. Turn in the instruction lockdown valve jackscrew on the fuel tank solenoid valve(s). See Fig. 7 . Perform
COMPRESSED NATURAL GAS FUEL LINE VENTING . Disconnect the fuel fill line from the fuel
fill valve. See Fig. 9 . Connect the Fuel Venting Kit (164-R0911) and Adapter (134-00255) to the fuel fill
line. See Fig. 10 .
2. Connect the Grounding Cable (134-00121) to the fuel fill line connection. See Fig. 11 . Connect the
grounding cable to the ground rod. Connect the Fuel Filler Neck Venting Kit (134-00117) to the Venting
Hose Assembly (134-00118) and adapter. See Fig. 12 . Connect the fuel venting kit to the fuel filler neck
venting kit. See Fig. 13 . Connect the venting hose assembly to the vent stack. See Fig. 14 .
WARNING:
Make sure the jackscrew in the Instruction Override Tool (134-00050) is
retracted fully (counterclockwise) prior to installation into the fuel
tank solenoid valve. Installation of the override tool in the venting
position will cause natural gas to be immediately released.
NOTE:
On vehicles equipped with an extended range fuel tank, the jackscrew can
be reached through an access hole in the vapor retaining cover.
NOTE:
Solenoid diagnostics must be completed on all tank solenoid valves prior
to venting. All fuel tank solenoid valves must be in the locked down
position.
WARNING:
Make sure that the jackscrew in the Instruction Override Tool is
retracted fully (counterclockwise) prior to installation into the fuel
tank solenoid valve. Installation of the override tool in the venting
position will cause natural gas to be immediately released
