Jim Callow will remember the old-fashioned systems where the driver had to screw lengths of pipe together and then manually pump the fuel via a handle; a very slow and messy process.

These days our driver arrives at your property and confirms your order on his computer. They then select the required oil volume from the appropriate tank compartment on the vehicle, open the valves and pull the lightweight hose to your tank. We carry roughly 140ft of pipe which is plenty to access most tanks we come across.

The really clever bit comes after the driver connects the pipe to your tank – their key fob allows them to start and stop the tanker pump all from the safest spot to ensure no spills; right by your tank. If the fob doesn’t work for some reason, then they have a backup gun on the pipe that will shut off the delivery. Our next vehicles will have a fob which shows the lorry meter reading as well, providing even more control over the delivery.

We use a ‘dry line’ delivery system. Once the last litre of your fuel has passed through the meter, a valve closes, leaving the line full of your fuel. The system then automatically introduces a large volume of air into the pipework, pushing your fuel from the pipe into your tank and purging the line clean for the next delivery.

You might sometimes see the delivery pipe bucking and jumping around; this is quite normal and indicates the air passing through the line. The empty line is then light enough for the driver to pull back to the lorry. When our driver returns to their vehicle your invoice will have already been printed out showing the unit price and litres delivered. Our meters are checked and sealed by Trading Standards, so you can be confident you always get what you pay for.
