Audi VW Fuel Tank Filler Neck - Genuine Audi VW 4D0201301T

Product Information

The fuel tank filler neck hose is a flexible connection between the fuel filler neck and the fuel tank. It allows safe transfer of fuel during refueling while sealing against leaks and preventing vapor escape. Constructed from fuel-resistant rubber or reinforced synthetic material, the hose is designed to withstand constant exposure to gasoline, ethanol blends, and varying temperatures. A properly functioning filler neck hose is essential for safe fueling, emission control, and preventing fuel odors.

• Fuel leaks or strong fuel odor near the rear of the vehicle – caused by cracks or deterioration in the hose.
• Difficulty refueling or fuel backing up – due to blockages, kinks, or collapsing hose walls.
• Check engine light related to EVAP system – from air leaks or vapor loss through a damaged hose.

About Genuine Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Audi parts box and find an OEM branded part inside, simply with the addition of an Audi logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
