PQY Billet Aluminum Fuel Cell Gas Cap – 12-Bolt 5.343" Spacing, Black Anodized, Rubber Gasket

This PQY billet aluminum fuel cell gas cap is a screw-down, 12-bolt replacement cap that offers a durable, easy-fill alternative to factory plastic caps and includes a rubber gasket for a secure seal.

If you run an aluminum or bolt-pattern 12-hole fuel cell and want a robust, serviceable filler cap, this PQY cap is machined from 6061 billet aluminum to replace the stock plastic flip-top style. It installs as a bolt-on flange for cells with 5.343" bolt hole spacing and is anodized black for a clean, low-profile look. The twist-on design gives faster, more convenient refueling and the supplied rubber gasket helps keep dirt and moisture out of the tank.

How does this cap improve fueling speed and convenience?

The screw-down twist cap removes the need to pry open a hinged plastic lid and makes topping off fuel faster and less fiddly—useful in pit or workshop settings. The threaded action allows controlled opening and closing that stays flush when secured.

• Twist-on cap for quicker access than flip-top designs.
• Flush-mount profile keeps the cap from catching on gear.
• Solid aluminum construction resists warping under heat.

Will this fit my 12-bolt fuel cell and what measurements matter?

This cap is intended as a direct replacement for many 12-bolt aluminum fuel cells with 5.343" bolt hole spacing. Because mounting patterns vary, measure your existing cap’s bolt spacing and hole diameter before ordering to ensure compatibility.

• Designed for 12-bolt fuel cells with 5.343" bolt spacing.
• Bolt-on flange style requires matching hole pattern.
• May need minor hole-size modification in some installations.

What materials and sealing features does the PQY cap use?

The filler cap is CNC-machined from 6061 billet aluminum for strength and durability in high-performance environments. It arrives clear-anodized in black and includes a rubber gasket to improve the seal against contaminants and evaporation.

• Constructed from 6061 billet aluminum for longevity.
• Clear anodized black finish for corrosion resistance and style.
• Supplied rubber gasket helps keep out dirt and moisture.

Are there installation notes or limitations I should know?

Installation is straightforward for compatible 12-bolt cells, but some cells may require enlarging or adjusting the hole size to accept the flange and bolts. Keep basic hand tools and proper fasteners on hand and check the gasket seating for an even seal.

• Includes gasket; bolts not always included—confirm package contents.
• Some fuel cells may need hole-size modification for fitment.
• Check original cap dimensions before purchase to avoid surprises.

Who is this for: This PQY billet aluminum easy-fill fuel cell cap suits racers, track-day enthusiasts, and mechanics who want a more durable, quicker-to-use alternative to plastic filler caps. It’s ideal for vehicles with 12-bolt fuel cell mounts or anyone upgrading to a metal cap for improved longevity, easier fueling, and a flush, professional finish.
