Install Your Fuel Vault
No modifications required. Install in minutes with basic hand tools.
Step-by-step instructions
Follow these four simple steps to secure your truck’s fuel system.
Unbox & verify
Verify all components are included: your Fuel Vault cover(s), your existing screws or new security screws purchased from us as mounting hardware, the lock, and a set of keys.
Position the cover
Remove your existing exposed fuel bezel screws and set them aside. Align the Fuel Vault cover over the exposed fuel cap area on your work truck, using the screw holes to confirm orientation.
Secure & fasten
Using the existing screws or the new security screws, secure the cover in place. An impact driver is best for the security screws — they are larger in diameter to grip and draw the door firmly into the bezel and sidewall. Caution: do not over-tighten, as excessive torque can break the screws.
Test & lock
Test the locking mechanism with both provided keys. Verify the cover is secure and the fuel cap is fully accessible when unlocked.
Security screws matter
For maximum protection we recommend replacing the factory screws with our tamper-resistant security screws. They use a specialized drive to keep thieves from simply unscrewing the cover, and their larger diameter draws the door tightly into the body. Screw packs are available on the products page.
