Audi Fuel Return Hose - Genuine Audi 4G0201220B

Product Information

A fuel hose is a flexible tube designed to transport fuel from one component of the fuel system to another, such as from the fuel tank to the fuel pump or from the pump to the engine. Made of rubber, synthetic materials, metal pipes, or reinforced rubber, fuel hoses are built to withstand the pressure, temperature, and chemical exposure that comes with handling fuel. Fuel hoses are essential to the proper functioning of the fuel delivery system and the overall performance of the engine.

• Fuel Leaks: The most obvious and dangerous sign of a failing fuel hose is a fuel leak. Leaking fuel not only causes performance issues but also poses a significant fire hazard.
• Fuel Pressure Loss: A damaged or leaking fuel hose can cause a drop in fuel pressure, leading to inconsistent fuel delivery to the engine. This may result in hesitation during acceleration, poor fuel economy, or misfires.
• Decreased Fuel Efficiency: Leaking fuel due to a compromised hose can cause fuel wastage, which will reduce your vehicle’s fuel efficiency.

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.
