Expansion Tank (Austin America Only)

This tank is located adjacent to main fuel tank to provide storage for any overflow from main tank caused by fuel expansion or parking at a steep angle with a full tank of fuel. This fuel will be returned to the main tank by the venting action as fuel is used from the tank. Expansion tank is connected to a carbon canister at the front of the vehicle by a vent line and fuel vapors are absorbed by the activated carbon in the canister. Vent line also acts to maintain atmospheric pressure in the fuel tank by admission of air through a filter pad in the bottom of the canister. Location of expansion tank (above main tank level) will prevent any liquid fuel flow to the canister.
