Hi there chaps having problems with our 2.0HDI engine starting. Takes for ever to fire up. Turns over and over and eventually starts. Fuel filter changed,no effect.Was some metal filings inside housing which is worrying. I decided to investigate fuel tank pump. Once i removed it i was shocked to find that there where only to wires going to the sender float.There is no pump inside housing ? Where is it ? What pressurizes the fuel system when turning on the ignition ?
