Nothing ruins your day like discovering someone drained your diesel tank overnight. Fuel theft is a real problem, especially when you’re parking tractors in remote fields or leaving equipment at job sites. This keyed locking fuel cap puts a stop to fuel thieves while keeping your tank sealed tight against dirt and moisture.
What You’re Getting
- Secure keyed lock mechanism that prevents unauthorized fuel access and tampering
- Proper venting system that maintains correct tank pressure while your engine runs
- Weather-sealed construction that keeps contaminants out of your fuel system
- Male threads designed for direct replacement of your original cap
- Two keys included so you can keep a spare in a safe location
Built for Real Farm Work
This cap is designed for John Deere tractors where fuel security matters – whether you’re working remote fields, custom farming, or just want peace of mind when equipment sits overnight. From utility tractors handling livestock chores to big row-crop machines during planting and harvest, protecting expensive diesel fuel makes good business sense.
Made to Last
Tisco builds this cap to handle everything farm life throws at it. The locking mechanism is designed to resist forced removal attempts while still giving you quick access with the key when it’s time to refuel. The seal stays flexible through temperature swings and keeps doing its job season after season.
Installation Notes
Installation is straightforward – just remove your existing cap and thread this one on in its place. Test the locking mechanism after installation to make sure everything works smoothly. Keep that spare key somewhere safe but accessible – you’ll thank yourself later if you ever misplace the first one.
