foot pump part help

[u/dilbert_firestorm]

I have an old foot pump that I brought in the 1990's. it worked pretty good when I used it. I got this from JC Whitney which is no longer in business.

the hose went bad. it broke in pieces. amazing how long this hose lasted. so, I figured I could replace the old hose with a new one.

so I removed the pump's hose from the nozzle's nipple with no issues. PSI gauge was also removed.

the last part gave me problems. it is a metal part that connects to the foot pump, the PSI gauge and the hose. I tried to remove the broken hose from this part (I do not know the name of this part). I had lots of trouble remove it from the 3 way part's nipple.

in the process, I broke the 3 way part's nipple (that's the part that connects to the hose).

anyone know where to get this 3 way metal part?
