Default I broke a vacuum orifice

So I broke one of the vacuum orifices on my 1995 2.5 Liter. Does anyone have a part number or source for a new one. I'd rather use a normal vacuum connector but the orifice has a specific size. It's the orange thing circled at the 6 o'clock position in the photo. I've tried a junkyard but not many old Daks there.

Update for part#

There is a 94-96 part manual you can download from the Sticky FAQ section.

Hey, I've been searching the parts manual but I can't seem to find it.

Try searching through Dorman brand vacuum tubing connectors. I believe they might have all kinds of stuff that you might be able to use. Worth a look-see.

I have a 1990 - 1993 parts manual. This is where I found the vacuum diagram for the 2.5L. Is this where you were looking in the 95 manual?

EMISSION CONTROL VACUUM HARNESS 2.5L ENGINE N BODY - 1990
Figure 25-1100

I can't take credit since Bronze found the correct part name but search the parts catalogue with "emissions control vacuum" and it will take you to the right section if you click through to the fourth hit. There is a picture of it indicating it is part 11 on the list. If you scroll down there are two more pages with the same prt in the diagram and same part number.Part# 5303 0290

Odds are it has been long discontinued.

Wish I had an extra to send you. Betcha if you just scrounge around looking at other 80s and 90s vehicles you'll be able to find something that works. Fords and GMs also had weird vac connectors and you just have to find one with at least three ports--if it's got more you can just block off the unused ones.

Unfortunately that's not exactly possible in my state because there's no pick and pulls. Bordering states have 'em though.

It's just a three tube connector. Run some extra hose and use a generic one. It won't look right, but it'll work. I had to do that on the computer vacuum controls on my old Mercedes 380SL. (There's a reason computers are electronically controlled today.)
