Focustronic bulk replacement parts thread (Mastertronic / Alkatronic / Dosetronic)

I took pump A and Pump C hoses out and Pump uses 16# from JIH PUMPS and Pump C uses 14#, specs can be found on the tube size chart in previous messages,
 
ok folks, here is what I found for Pump C - does this seem correct info - if yes then it is same specifications as 16# tube based on the chart above, that means pump A and Pump C is same size tube only difference is the end connectors which are smaller than Pump A. any one can confirm?

I just replaced my A and C tubes this weekend, they are def different sizes, and the connectors are too.

Does anyone know where you can source these joints for the Alkatronic A & C connectors? I have found the appropriate #14 and #16 tubing but need these connectors to prep some replacement cuts. Thx!

Holy markup Batman!!!
Do you know where to get the hose for Alkatronics inner tubing pump A it should be the same tubing for the mastertronics inner tubing stepper pump. I searched AliExpress and couldn’t find it.
 
These filters work for my Alkatronic. No metal.

Has anyone recently found a replacement for the Alkatronic/Mastertronic filters? It looks like these don't exist anymore on Amazon. All the newer listings have paper filters with magnets.
 
anyone found replacement needles or an alternative maybe slightly shorter?
