Caparo Rightfuel

£29.99

You can’t ignore the Rightfuel, as it simply will not allow unleaded into the tank. It replaces the standard cap, screws into the filler and has a simple adaptor to allow it to fit most cars. The flap won’t open until releases in the tube are pressed at the same time, which is only possible with
the larger diesel nozzle.
