I have a 1983 Mercedes 300D Turbo Diesel - 5 cylinder - automatic transmission - W123 - 617 engine.

It looks like I will be replacing the Fuel Injection Pump - what pumps are compatible? I may be looking in junkyards and want to be sure I am pulling the right ones before bringing it back and finding it was wrong.

Does anyone have any info on compatible serial numbers or where to find out?

I don't know, but if you find out I have one on Fleabay right now off of a nonturbo.

Any injection pump from a 81-85 300TD, 82-85 300D/CD, 81-85 300SD and 79-80 300SD.

A non-turbo injection pump will work in a pinch but you will be forever limited to 88hp.
