GM must have made 10's of millions of these intake vacuum fittings yet I see no repops.

1/8-27 NPT one end, 5/32nds or 1/8 other end.

eBay for sure…

I get that stuff from Inline Tube.

They have that fitting as well as the PCV, the vacuum control valve, and other miscellaneous vacuum fittings at the back of the intake.

Here's a link

Unfortunately neither one of those are what I am looking for. These are the brass block-headed bits that screw into the manifold itself and feed vacuum.

Unfortunately that link I provided did not work correctly. It doesn't take you to the page I had actually tried to link.

You'll have to search Inline Tubes site and you'll see all those vacuum fittings for the intake you're looking for.

You have to go to engine and then a couple sub categories, intake, etc.... If you search around you'll find it. I had it on my screen but difficult to do. It's not the easiest site to fish around and search words don't always bring up what I think they should. Might be best to call.

A pic would be great. I may have a rectangular brass fitting with a hose nipple on one side and threaded on the opposite side. I’ll look around tomorrow.

FOR INFO:
Intake Manifolds (with the fitting on the front of the intake plenum) are NOT just a typical
90 degree nipple fitting. The Fitting is several inches long and has a feed port on the
fitting that receives plenum signal from both the upper plenum and the lower plenum.

A very unique fitting. Installing a hardware store 90 degree fitting will not have the same PCV performance as a factory fitting.

Try this link,

This is the factory style large 1/4 or 3/8 pipe vacuum fitting on the front of the intake that has a very small 5/32 nipple for vacuum hose

and here is the link for the PCV fitting that Tom is talking about that has the long extension underneath to reach the lower plenum

There are many others in various forms but you'll have to search for it, or better yet provide a pic of what you are looking for.

I generally use the type in the link posted by misterp266. They are basically a plumbing fitting. Most factory fittings have a single bulge in them. The plumbing ones have the stepped barbs. The hoses do not slide off easily if removal is required.

they look like this:

Link?

[Scarebird]

[Formulajones]

A link to a picture?? Or a picture?

Your post just says "they look like this" and there is nothing there....?
