30 MAINTENANCE AND LUBRICATION
Removing Pressure Before Working on the Tanks
If the fuel lines between the tanks or the tanks themselves must be worked on, the
system must be totally "bled" of fuel, including the tanks. With a minimum amount
of fuel in the tanks, open the manual vent valves on the tanks until the tank pressure
gauges read zero.
Note: If possible, try to service the tanks after the vehicle has used most of its
on-board fuel.
WARNING
Never bleed the tanks in an enclosed
area. Be sure there are no sources of
ignition in the area.
Moving a Vehicle Using Auxiliary Fuel
When LNG tanks are not fueled or have been removed, the vehicle may be moved by
connecting an auxiliary CNG (compressed natural gas) tank to the connection located
on the left side frame rail behind the front inside of the fuel tank on the driver side.
CAUTION
Use a CNG tank with its own pressure
regulator. Pressure must not exceed 120
psig at auxiliary tank connection valve
(see illustration).
