A fuel filler housing is the enclosure surrounding the fuel filler neck, typically located behind the fuel door. It provides a secure mounting area for the fuel cap and filler tube while protecting the refueling area from dirt, moisture, and debris. The housing also ensures proper alignment of the fuel nozzle during refueling and often integrates a tether or holder for the fuel cap. Over time, it can wear out or become damaged due to frequent use, corrosion, or impact.

• Physical damage – cracks, broken mounts, or misalignment around the fuel door or filler neck.
• Rust or corrosion – especially in metal housings, leading to weakened structure or fuel cap fitment issues.
• Fueling difficulties – loose fitment, cap not sealing properly, or nozzle not seating correctly, sometimes triggering the check fuel cap light.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

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