Fit a Diesel Head to prevent you putting petrol in your diesel vehicle, and say goodbye to catastrophes and the cost of repair. The unique diameter of a diesel pump nozzle is the key to accessing your fuel tank. With a Diesel Head in place only a pump nozzle can be inserted into your tank.
Just fit and forget!
Once the Diesel Head fuel cap and internal collar are fitted to your fuel tank inlet, you’ll never accidentally misfuel and pump petrol into your diesel tank again. Diesel Head is designed to fit most vehicles easily and securely. Check if it fits your vehicle.
Whether you’re a corporate fleet owner, farmer, small business owner, multi-vehicle family, or a concerned parent – Diesel Head will give you peace of mind. We’ve even got one that locks if your vehicle’s fuel cap can be opened from the outside.
