Fuel Filler Hose: Description and Operation
FUEL PIPES AND HOSES
Fuel feed and return pipes (lines) and tubes carry fuel from the fuel tank to the fuel rail and back to the fuel tank. These pipes and tubes are attached to
the underbody of the vehicle and must be inspected for kinks or dents which may restrict fuel flow.
Fuel vapor pipes and hoses carry fuel vapors from the fuel tank to the evaporative emissions canister located in the engine compartment (4DR : the rear
side of fuel tank). The fuel vapors are stored in the canister when the engine is not running. When the engine is running at normal operating temperature,
and the accelerator pedal is depressed, the engine control module (ECM) will command the evaporative emission solenoid purge valve to open and allow
the stored fuel vapors to be purged into the intake manifold and be absorbed into the combustion process.
