Welcome to the home of Diesel Head, Britain's premier misfuelling prevention device

The strength of this anti-misfuel device is its simplicity - one size fits almost all!

There are no packs of adaptors, spacers or collars to hang a misfuelling prevention device from your tank or the diesel pump itself. It is simply a machined precision device, made of the finest materials and designed to clamp firmly to the filler point/inlet of your diesel tank.

You will know as soon as you handle our misfuelling prevention device that it is the right one for the job - testament to the skills and commitment of the Diesel Head inventor, Lee Steadman, and our team of engineers.

Fit a Diesel Head to prevent you putting petrol in your diesel car. Say goodbye to the cost of repairs and the consequences of disruption to your plans.

This website will confirm why the Diesel Head misfuel prevention device is the perfect product for you to fit and forget - providing peace of mind at the pump that you will never misfuel.
