Fuel Caps

A secure, properly sealing fuel cap is a small component that plays a big role in your vehicle's performance and reliability. It prevents fuel from sloshing out, keeps dirt and moisture from entering the tank, and maintains the correct pressure within the evaporative emissions system. A failing or missing fuel cap can trigger a check-engine light, cause raw fuel smells, and reduce fuel economy through evaporation.

Our fuel cap collection covers a wide range of styles and applications, from straightforward OEM-style replacements to locking caps that deter fuel theft and tampering. You'll also find vented caps designed for older vehicles or custom applications where tank ventilation is handled at the filler neck.

  • OEM-style replacements that match factory fit and function
  • Locking caps with pick-resistant tumblers for added security
  • Vented and non-vented designs to suit your fuel system layout
  • Durable materials built to withstand fuel exposure and weather

When choosing a fuel cap, verify thread pitch, diameter, and venting requirement against your vehicle's specifications. The right cap seals tightly with an audible click and maintains the integrity of your entire fuel system. Browse the collection below to find the correct cap for your application.
