Hi, my sons 1.8tdci 2006 cmax has been stalling. Garage check shows fuel pressure sensor fault. It is £400+ to replace but they said source one from elsewhere and they'd fit it unless we do. So we are having trouble identifying it. We can see its a delphi but cant see any markings at all. It is a star shaped type rail its screwed into. Can anyone tell us the correct type we need and is it a simple case of unscrewing it and replacing or is it a complicated garage job? Thanks guys.
