Fuel Tank Unit: Description and Operation
Evaporative Loss Flange
Evaporative Loss Flange
The flange is mounted to the tank by a seal (4 Fig.1) and locking ring (5 Fig.1), it has three external outlet ports and one electrical connection.
The large port (1 Fig.2) is capped. The tank vapor vent being connected directly from a tube on the tank to the fuel filler neck (6 Fig.1).
The intermediate port (2 Fig.2) has a "Legris" quick- fit connector moulded in, and allows for over pressurization; it is connected to atmosphere by a
nylon pipe the outlet of which is underneath the vehicle.
The small outlet port (3 Fig.2) is used for fuel tank venting and uses a nylon pipe to connect the tank to the charcoal canister located at the front of the
vehicle. For cars not fitted with evaporative loss control, the pipe is vented directly to atmosphere via a hose passing underneath the car. In both cases a
Tank Pressure Control Valve is included in the line, controlled by manifold pressure.
