Electric Fuel Pump
DESCRIPTION AND OPERATION
Fuel Vapor Valve, Ranger
The evaporative emission valve (9B593) makes use of a small orifice that tends to allow only vapor and not
liquid fuel to pass into the line running forward to the fuel vapor canister. The evaporative emission valve
mounts directly into the fuel tank (9002) using a rubber grommet.
Fuel vapors contained in the sealed fuel tank are vented through the orificed fuel tank evaporative emission
valve in the top of the fuel tank. The vapors leave the evaporative emission valve through a single vapor line
and continue to the fuel vapor canister in the engine compartment for storage, until such time as they are
purged to the engine (6007).
