This system consists of
a fill vent valve, fuel shut-off valve, fuel cut valve (for roll over),
two way valve (pressure/vacuum relief), fuel liquid/vapor separator which
is installed beside the filler pipe, charcoal canister which is mounted
under the rear floor LH side member and protector, tubes and miscellaneous
connections.
While refueling, ambient
air is drawn into the filler pipe so as not to emit fuel vapors in the
air. The fuel vapor in the tank is then forced to flow into the canister
via the fill vent valve. The fuel liquid/vapor separator isolates liquid
fuel and passes the pure vapor to the charcoal canister.
While the engine is
operating, the trapped vapor in the canister is drawn into the intake
manifold and then into the engine combustion chamber. According to this
purge process, the charcoal canister is purged and recovers its absorbing
capability.
