VW Fuel Tank Hose - Genuine VW N90123501

Product Information

A fuel tank vent hose is part of the evaporative emissions (EVAP) system that allows fuel vapors to escape from the fuel tank and be routed to the charcoal canister for storage and later combustion. It helps regulate tank pressure, prevents fuel vapor buildup, and supports proper fueling flow when adding gas. A properly functioning vent hose is essential for emissions compliance, fuel efficiency, and safe tank operation.

• Difficulty refueling, with the pump nozzle shutting off frequently due to poor venting.
• Strong fuel odors, caused by cracks or leaks in the hose.
• Check Engine Light (EVAP-related codes), triggered by vapor leaks in the system.

About Genuine VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW 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 VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly 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.
