Hi There, Im just looking for anyone who might also have had problems replacing their hand primer pump (in the models that have them) I have an 85 300TD on and the pump seems to be the source of power loss problems. (air leakage) However I went and bought a new one and when I put it in it wouldnt start at all.

I even had it taken to some pro mechanics and they eventually figured out that by putting back tho old primer pump the car would start again. It was installed properly as I did it and also the mechanics did it on separate occasions. Its pretty simple.

Also if anyone knows off hand the two part number differences between the new and old style pumps I would love to have them so I can refer them to the Mechanics or parts searches.

Thanks
