Fuel System Manual Control Valve (CNG): Description and Operation
Fuel Fill Check Valve (CNG)
DESCRIPTION
Frame Rail Mounted Check Valve
Two different one-way check valves are used with the CNG fuel system. One of the valves is located integrally within the fuel fill receptacle. The
other valve is located in the fuel fill tube near the top of the left rear shock absorber.
OPERATION
Both valves are used to keep fuel from escaping from the fuel fill receptacle (fuel supply will only travel toward fuel cylinders).
