I was frustrated as a failed to take of my diesel primer pump, reaching from many angles until I heard a snap. I breaking of something that appears to be vacuum related. It connects to a hose that leads to the brake booster. Can anyone Identify the part.

Its a combination check valve and T. It probably has a part number on it.

It is the vacuum line. If you do not want to buy a new one, it can be repaired. Drill it out and epoxy a short stub vacuum tubing (a little over 1/2" long). Next time, remove whatever maybe in the way that can break.

The old plastic nipple get brittle with heat and a lot of years.
This is one area you need to be careful to not use as a arm rest.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

Common problem, I think. As others have already suggested, epoxy and a piece of vacuum tubing will work, at least until you can get a replacement. The prices for replacements seem to have come down in the past few years.
