Question about this product?

We're happy to help.

Nobody likes filling up, right? But this Billet Fuel Filler Cap is beautifully over-engineered in customary RacingLine fashion to give an exquisite feel and beautiful appearance. Makes pumping gas a little more of a pleasure! This cap for 'push & twist' cap applications.

RacingLine’s replacement Fuel Cap is one of those upgrades that will delight you every time you use it. Machined from a solid billet of 6061 aerospace-grade aluminum, it’s lovingly hand-polished then anodized in glossy midnight black with laser-etched logo. It closes with a satisfying engineered 'click' each time you fill up. Make refueling great again! A new pressure relief valve integrated into the cap always maintains balanced tank pressure. The design still allows you to prop the cap in the factory locater in the filler flap while you're filling up. And it comes complete with new rubber o-ring seal and locating tether to match all the functionality of the plastic factory cap. This version of the cap is for 'Push & Twist' type caps, typically found on newer and larger VWG vehicles. If yours is not push & twist, RacingLine also offer a screw-in cap, typically for older models.

Can I return a part after it has been installed?

Generally, installed or used performance parts cannot be returned. We strongly recommend verifying vehicle fitment and inspecting the product before installation.

Can I cancel my order after it has been placed?

We begin processing orders as quickly as possible. If you need to cancel, contact us immediately. Once an order has entered fulfillment, been submitted to a supplier, or shipped, cancellation may no longer be possible.

Will this part fit my vehicle?

Fitment varies by year, make, model, trim, engine, and drivetrain. Use our vehicle fitment information to confirm compatibility. If you're unsure, contact us with your VIN and we'll help verify fitment before you order.

How do I know if this is the right upgrade for my build?

Not every upgrade makes sense for every vehicle or build. Tell us your vehicle, current modifications, and performance goals, and we'll help determine whether this product is a good fit.

Are the products you sell authentic?

Yes. We source products through established manufacturers and authorized distribution channels. We do not sell counterfeit or imitation performance parts.

Is professional installation recommended?

For most performance components, yes. Proper installation is critical for fitment, reliability, and performance. Some products may also require specialized tools, programming, tuning, or additional supporting modifications.
