This is where the price increases by a penny when the fuel nozzle is replaced back onto the fuel pump. As fuel passes through the pump a pulser rotates and this passes the information to the pumps processor which registers the volume delivered and the price is calculated by the computer. When fuel prices are high it only takes a little movement for the pump to register that increase.

The UK law says any error with a pump must be less than 2 pence.

Before a pump can be put into use in the UK, it must be granted a Certificate of Approval issued by the National Weights and Measures Laboratory. Part of the Laboratory’s approval process is that they must be satisfied with the method of price computation.
