The misfuelling prevention device

Counting the costs of misfuelling – petrol in diesel

A litre of fuel may not be as expensive as a pint of beer but the cost can still be a concern for drivers and representative organisations who look to the exchequer to act and cut duty and retailers to pass on any falls in fuel prices. Meanwhile, motorists can take steps themselves to avoid wasting money as a result of misfuelling.

Inventor of the Diesel Head Misfuel Prevention Device that stops petrol in diesel

British inventor Lee Steadman, designed and engineered the Diesel Head Misfuelling Prevention Device to prevent diesel drivers mistakenly pumping petrol in diesel tanks.  Lee says: “Misfuelling can cost a motorist five times. First, the cost of the wrong fuel – petrol  – pumped in; second the cost of recovery and flushing the tank out; third the cost of the diesel to be pumped in; fourth is the cost of repairs to the engine if the driver started up. There is also a potential fifth cost of vehicle hire which might be required to allow the motorist to be productive and get on with life while repairs are undertaken.”

Motoring gadget prevents petrol in diesel

Motorists who purchase this driving gadget simply fit it to the head of the vehicle fuel inlet pipe and then forget about misfuelling.  A petrol nozzle is smaller in diameter than a diesel fuel nozzle and is simply too narrow to activate the Diesel Head aperture, which can only be triggered by a ‘diesel’ diameter nozzle to allow access to the tank, thus protecting the vehicle.

“While the Diesel Head device may not be able to influence the Head of the Treasury to reduce the tax take at the pumps or retailers to be prompt in passing on price drops, it should get a high five for keeping the driver on the road and being an example of great British design, engineering and innovation,” concludes Lee.
