Default Injector POP TESTER that works with the d24 injectors (old vw idi diesel)

May I ask, what kind of injector pop tester do you have, or what injector tester are you using?
Can you (or anyone) refer me to one that works with our d24/d24t injectors? There are many available on eB@y but the desired Bosch versions cost hundreds of dollars.

Maybe this?

It does not have the most ideal range on the gauge (our injectors pop open in between ranges of around 1700-2400). The best would be to have one where the gauge is calibrated from 0-3000psi for easier fine-tuning. The one I linked goes up to 9000psi.

But, would this work? I cant judge just by looking at the pictures. What are you using to test yours?

What is the size and thread pitch at the top of the d24/d24t injector?
Isn`t it 12mm x 1.5? THX

What about the other end of the fuel hard pipes that connect to the d24 injection pump at the delivery valves? What`s the size there, I have no idea...
