Fuel Filler Hose - North AMERICAN Specification Vehicles

The neck of the fuel filler pipe is positioned at the rear of the vehicle, above the rear right wheel. The fuel filler pipe and fuel filler cap are covered by a molded plastic fuel flap.

The fuel filler flap has the option to be non-locking or electrically locked when the vehicle is locked.

The fuel filler cap is a conventional screw-in type which is secured to the vehicle with a lanyard. The fuel filler cap must be securely fitted to provide that the fuel tank venting system is sealed and potential fuel loss prevented. The fuel filler cap has a ratchet locking mechanism, it should be screwed-in to a torque of three audible clicks. The three audible clicks provide to make sure it is correctly tightened.

For the North American Specification (NAS) vehicles the fuel filler cap has a single click ratchet mechanism. The single audible click confirms the cap is correctly tightened.

The fuel filler pipe is a stainless steel fabrication which is secured to the vehicle body with two brackets and nuts. A metal stub pipe, attached to the fuel filler neck, provides for the attachment of the breather.

The fuel filler hose attaches to a stub port at the rear right of the fuel tank which incorporates a check valve. The in-line check valve is mounted inside the fuel tank inlet stub port, and is retained in the closed position by a spring. The check valve is only opened when the vehicle is refueled.

A breather is connected between the fuel filler neck and the fuel tank. The breather enables the fuel tank to be filled, allows for expansion of the fuel vapor and controls the fuel cut off during filling. The fuel vapor is routed to the Evaporative Emission (EVAP) canister. For additional information, refer to: Engine Emission Control /Evaporative Emissions .
