Role and Importance of Filler Necks in Automotive Cooling Systems

A fuel filler neck is part of an automobile’s fuel system that makes moves from the outward fuel cap to the OEM fuel tank. The rubber seal on the peak of the cap helps prevent fuel and its vapors from leaking. These high-quality filler necks fill up vents that are threaded and an O-ring that suits nicely the inside part of the fill design, sealing and filling it.

Filler caps are tiny and simple parts. Yet, their role is very crucial because:

1.                They help in keeping oil or fuel locked and prevent it from flowing out of it.

2.                They ensure dust and waste stuff don’t get inside the engine.

That’s why it is important to know the uses of filler neck and caps and how one can make out bad filler caps as well. For example, if smoke comes out of the Filler Neck/Cap, it is a matter of concern and helps you to know if the smoke is coming out of the filler neck or cap. If your filler neck or cap is not positioned correctly, if it is of oil or fuel, you’ll observe some symptoms like:

•                 Oil/gas seepage

•                 Reduced fuel economy

•                 Reduced engine performance

•                 Check engine light

So, ideally, the fuel filler neck is the main point of entry for fuel in an automobile. It helps in getting fuel from the pump nozzle down below to the fuel tank. Some filler neck descriptions are as follows:

•                 The double coat on it provides toughness for corrosion protection.

•                 It uses a particular conductive paint that helps in dissolving the static charge.

•                 It has a ground wire for safeguarding if necessary.

•                 Some models are available in an upgraded capless design

•                 These are designed in a way that they can meet the manufacturer’s specifications

•                 Lifecycle, temperature, and fuel soak are vigorously tested to make sure of good performance
