Description
The fuel cap also known as the diesel cap, gas cap or petrol cap sits behind your cars fuel door. It can be removed so that fuel can be put into your car. The fuel cap protects the inside of your fuel system from dust and other contaminants. It also prevents issues with your cars evaporative emissions controls by sealing the entry point to the fuel system shut.
The Fuel cap is often considered an unimportant component. However, operating your car without a fuel cap can lead to problems. When there isnt a fuel cap protecting your fuel tank, debris such as dust and dirt can find their way into your cars fuel system. This can cause your fuel filter to become blocked, restricting the flow of fuel to your engine.
The fuel cap helps control the level of hydrocarbon emissions from the petrol in the fuel tank into the atmosphere, then a correctly tightened working fuel cap is vital.
