Common Rail Fuel System

The common rail diesel fuel system consists of an extra, under bonnet, fuel pump and fuel return lines. Also, a diesel cooler is fitted to the fuel tank return line. Unlike the in tank filter fitted to petrol derivatives, the diesel filter is fitted externally to the tank in an under bonnet location.

The extra pump is fitted before the fuel filter and increases the pressure to assist the fuel through any potential blockage of the filter during cold starts. The extra pump helps to ensure all engine fuelling requirements are satisfied in all conditions.
