We had a running fault on a 2002 Trafic DCI.
With a low pressure gauge between the filter and pump there was a priming pressure from the in tank pump of approx one bar (koeo).
With it running there was a negative pressure (sorry can't remember the reading) on the gauge from the vacuum pump mounted on the rear of the HP pump. As Tony says check the pump drive.HTH
