Once and for all, you have to set this straight: the fuel filler neck of your automobile is the part where the gas cap is placed or removed during fuel refills. When refilling fuel, you can check this component out for dents and cracks that may contaminate your fuel. Doing so will also avoid accidental falling of the fuel cap, which can lead to more chances of fuel seepage and entry of unwanted elements.The fuel filler neck is designed like an orifice; it has intake and discharge parts. The intake is mounted on the rear or side of the vehicle using bolts and a cap is fastened on it. Modern units are equipped with caps that have hinges and lock dials outside, making the fuel in the tank more secured. Older models are simply screwed on it each time fuel is refilled. The discharge end is attached to the fuel tank so the fuel can directly flow in. To ensure that the fuel filler neck will not be damaged by the impacts and movements of the vehicle, it is durably secured along the fuel system.The fuel filler neck is very important in containing the fuel. Under normal conditions, it is supposed to last the life of the vehicle.
