Oh, dear. Replacement pump and replacement injector lines? really? Help me grasp how/why that would be easier than rethreading the aneroid unit. I'm not thinking anything is wrong with the pump or the injector lines, but school me please.
it would be easier to replace it with good working parts than to try and find parts for or repair something which is NLA and very rare. i have one i can look at and send u measurements if you want, but its a very rare part. another easy solution for might be to just remove i and run the pump with out it. its a cool part though if you can repair it. do you have an pictures so maybe we can understand better what is leaking or broken?
and now that i read again, you might just need an o-ring
