Pump Nozzle Elements: A Comprehensive Overview

Hello,

With the VP TDIs, it was possible to swap the injector bodies between different engines (e.g., AFN and 1Z). While the opening pressures were slightly different, this didn't make much of a difference in everyday use. You could also choose cylinder heads based on the desired performance, and that worked well.

How does that apply to the pump-nozzle elements?
What components can be used in an AUY system, for example? Is there a list or overview of available components (I'm sure I'm not the first person to look for something like this, but at least I haven't found anything useful so far).

I once got a defective print head and opened it up following the instructions in this video. Replacing the print heads is still not a huge problem (provided you maintain cleanliness and exercise caution).

Thank you in advance!

Best regards,
