Intake manifold Brake booster plug
 
I will be installing a hydratech hydroboost brake set up in my Blazer. Because of this I need to plug the hole where the brake booster got its vacuum. Trucks with factory hydroboost have the plug in that location. I do not want to put a bolt in a hose!

Does anyone have the GM part number for that plug?

It will look like this but it is solid instead of hollow.

Years ago I tried to find the part number for that plug and never did find one for it. The part its self doesn't have a number cast into it either. But if you send me your address I'll send you this one.

Can’t you find and use a vacuum cap on the original fitting?

AC Delco #12559760. This is the part number for the nipple.

Edit: I see that you are looking for the part number for the plug. Looks like ICT billet make a billet plug that you could use. I have a couple around somewhere, but I cleaned and not I can't find anything lol

You wouldn't happen to have a part number for that bag full of them?

I sent it out Monday morning. I'll have to find the receipt from the PO to see what happened to it.

The luck I am having finding this plug is not working!

I had a vacuum cap on that port but the engine hiccupped and it took a long time to find the problem......... it blew the cap off, so I need a bag of the RIGHT plugs as I have 3 engines not using this port


Thanks
