Diesel Head Mis-Fuelling Prevention Device – Petrol In Diesel Protector, Replaces Fuel Cap (DH01/1)

We've all heard the horror stories—or maybe done it ourselves.

Putting petrol in a diesel engine is a costly mistake.

This little gadget, the Diesel Head, is designed to stop that from happening.

It's a modified fuel cap (part number DH01/1) that replaces your existing one.

It's engineered to accept only diesel fuel nozzles, so if you try to stick a smaller petrol nozzle in there, it just won't fit.

It's a simple, mechanical way to save yourself from a very expensive repair bill.

It's brand new, black, and ready to install.

If you drive a diesel, this is some cheap insurance.
