PQY Billet Aluminium Fuel Cell Fuel Cap — 12-Hole 5.343" Bolt Spacing, Black Anodized, Rubber Gasket

This PQY fuel cell cap is a CNC-machined 6061 aluminum replacement designed for 12-bolt fuel cells with 5.343" bolt spacing. Finished in black anodize for a low-profile look, it swaps into standard 12-hole bungs and includes a rubber gasket to help seal the tank opening. The screw-down design makes refueling simpler and more robust than many flip-top plastic caps while offering a neat, flush fit for race cars, track builds, or upgraded street projects.

How does this cap improve refueling and everyday use?

The threaded, twist-on design gives a smoother, more positive operation than hinge-style plastic caps. It’s easier to handle under stress or with gloves, and the metal construction resists wear from repeated use and fuel exposure.

• Twist-on action for consistent engagement and quicker refills.
• Aluminum body resists cracking or deformation common to plastic caps.
• Flush-mount profile reduces snagging and improves cockpit or trunk aesthetics.

Will this fit my existing 12-bolt fuel cell?

The PQY cap is built for the common 12-bolt pattern with a center-to-center bolt spacing of 5.343 inches. It’s intended as a direct drop-in for many aluminum fuel cells, but some installations may require minor hole-size adjustments at the flange.

• Designed for 12-bolt fuel cells with 5.343" bolt spacing.
• Includes bolt-on flange and rubber gasket for sealing.
• Verify your current cap’s hole diameter before installing to avoid modification surprises.

What materials and build quality can I expect?

Manufactured from 6061 billet aluminum using CNC machining, the cap balances light weight with durability. The black anodized finish offers corrosion resistance while delivering a clean, performance-oriented appearance.

• CNC-machined 6061 aluminum for consistent tolerances and strength.
• Black anodized surface for improved wear and corrosion resistance.
• Supplied rubber gasket to help keep dirt and moisture out of the fuel cell.

Are there any installation tips or compatibility cautions?

The cap installs through the 12-hole flange using the included gasket; however, some older or nonstandard cells may need the flange hole enlarged or slight modification. Keep basic hand tools ready and inspect the original bolt pattern and hole diameter before fastening.

• Check original cap hole size and bolt pattern before installation.
• Minor hole adjustments may be needed on some tanks—measure twice, cut once.
• Hand-tighten and seat the gasket fully to ensure a good seal before final torque.

Who is this for: This PQY billet fuel cell cap is aimed at racers, track-day enthusiasts, and vehicle owners upgrading worn plastic filler caps who want a durable, user-friendly, flush-mount solution. It suits builds that demand a neat appearance, improved handling when refueling, and a more robust metal alternative to stock plastic caps—provided the vehicle uses the common 12-bolt, 5.343" spacing pattern or can be adapted with minor modification.
