What is the Fuel Filler Neck?
The fuel filler neck is a part that links the gas cap and the fuel tank. It may be a metal hose that is soldered to the fuel tank, or a rubber hose that uses hose clamps to hold the neck to the gas tank. When the neck is metal, it is made of lightweight aluminum, steel or chrome plating. Modern necks are powder-coated to raise their lifespan. While they are planned to be long-lasting, corrosive chemicals can cause them to wear and rust over time. They will develop holes and cracks that let the fuel to leak out. Not only does this create a fire hazard, but it permits dust and debris to seep inside and reduce the performance of your vehicle. Accidents or collisions can also damage the fuel filler neck. While it can be temporarily patched with an adhesive, replacement is often the better long-term fix.
