ahh you're correct I did I must admit that was a mistake and was not intended I was more trying to explain the engine which was pictured. the PD is pump duse not the same as common rail I must admit. the PD has still not got a mechanical pump VE ( distribution pump ) on the side of the engine. it has a low pressure pump in the tank then a high pressure pump on the end of the camshaft the injectors also have a pump which is operated via a lobe on the cam hence the pump duse ie individual pump unit. they also have an electronic side built into the injectors which the VE engine doesnt.
