Billet Proof Designs OE-Style Vented Fuel Cap for Harley Touring 1992–2026 — Black, Right-Hand Thread, Leak-Resistant

This vented, right-hand threaded replacement cap recreates the original equipment fit and function for Harley touring bikes that use a fuel door. Built with durable nylon threads and a heavy-duty rubber seal, the cap is engineered to provide a leak-resistant closure while allowing tank vapors to breathe. Its compact dimensions and ratchet over-run protection make installation straightforward and prevent overtightening.

Will this cap fit my Harley touring model?

It fits Harley FLH and FLT touring models manufactured between 1992 and 2026, provided the motorcycle has a fuel door. Confirm that your existing cap uses right-hand threads (turn right to tighten) and that the fuel door opening matches the cap diameter before purchasing.

• Direct OEM replacement for part number 61274-92
• Compatible with Harley touring models 1992–2026 (FLH & FLT) that have a fuel door
• Right-hand thread—turn right to tighten

How does the cap prevent leaks and allow venting?

The cap combines a heavy-duty rubber sealing gasket with precision-molded nylon threads to create a robust, leak-resistant interface with the fuel tank. An integrated vent lets fumes escape and air enter the tank to prevent pressure or vacuum buildup during normal operation.

• High-quality rubber seal for a tight barrier against spills
• Nylon threads resist wear and cross-threading
• Vented design balances tank pressure and venting

Can I overtighten this cap or have trouble closing the fuel door?

No—ratchet over-run protection is built into the cap to stop over-torquing and ensure a consistent tightness. If the fuel door doesn’t close after installing the cap, the fix is simple: rotate the cap so the molded rib (mohawk) is perpendicular to the motorcycle backbone, then re-seat the door.

• Ratchet over-run prevents accidental overtightening
• Index the rib perpendicular to bike backbone for correct fuel-door clearance
• Easy installation and re-indexing if initial fit blocks the door

What are the cap’s dimensions and installation details?

The cap measures 2.68 inches (68 mm) across and stands 2.32 inches (59 mm) tall, giving it a compact profile that fits under most Harley fuel doors. It installs with right-hand threads and seats securely with the included rubber gasket and nylon-threaded body.

• Overall diameter: 2.68" (68 mm)
• Overall height: 2.32" (59 mm)
• Right-hand threads, vented, nylon thread construction

Who is this for: This cap is intended for Harley touring riders who need a reliable, OEM-style replacement for part 61274-92. It’s ideal for owners of FLH and FLT models (1992–2026) with a fuel door who want a vented, leak-resistant cap that matches original fitment and prevents overtightening, while remaining easy to index for correct fuel-door clearance.
