MAJOR COMPONENTS PRINCIPLES OF OPERATION ......................................................
Pressure Cup (1). The pressure cap attaches
to the fuel press adaptor (2) to seal off the
The pressure cap is attached to the converter
assembly with a safety chain so it is not lost
during use. To install the pressure cap on the
fuel press adaptor, engage the cap in the
adaptor, press down on the cap and turn the cap
clockwise until it locks in place. To remove the
cap, press down on the cap and turn the cop
counter-clockwise until it is free to lift off of the
Fuel Press Adaptor (2). The fuel press adaptor
mates with a standard refueling nozzle which
opens the poppet when engaged with the
adaptor, allowing fuel to enter the converter
Jet Sensor (3).
The jet sensor supplies
pressure to the pilot assembly which opens the
piston of the internal valve during the refueling
operation. When the tank is full, the jet sensor
shuts off the pressure to the pilot assembly),
closing the piston.
Pilot Assembly (4).
Pressure from the jet
sensor opens the pilot assembly allowing
pressure to unseat the piston in the internal
valve, allowing fuel to enter the tank. When the
tank is full the jet sensor will shut down the pilot
assembly, closing the piston of the internal
