Need help finding 15/32" booster check valve

[K85 Octane]

Ok peoples, simply looking for a brake booster check valve with a 15/32 input barb. I search using the measurements but come up empty. I can find 3/8 barb all day long, from Help or Dorman. I tried ordering one with my '85 Blazer as the search vehicle, came up 3/8". Then tried the '05 Yukon the engine came out of, which uses a 15/32" fitting off the back of the intake. I again came up with a 3/8" barb. I did one search at a local parts store and it came up "dealer only", which was odd.


I don't know how I ended up with a 15/32 check valve on my Blazer, but it has one. So.... they are out there. The CPP booster for my '68 came with the 3/8, no good. I'd much rather run the larger valve than to run an adapter that looks goofy.

Any help would be awesome.

PS> my Blazer is out of town and covered in tarps and straps, otherwise I would try to find a part number on it.

I tried to find one at the junkyard the other day with no luck. There were tons of 3/8 ones.

Was there one on the master /booster I gave you?

Some of them SUV's had some kind of electric pump mounted inline with the booster vacuum. Maybe those were the ones with the larger fitting?

I don't remember unfortunately. The valve that was in it is correct. I don't remember if I swapped valves when I installed yours or if I just swapped the whole thing in. I only have my brand new booster in the garage, with no valve. I don't know what happened to my first booster I had, prolly threw it away. I tend to throw stuff away immediately.

I've never looked at them that hard. I don't remember anything about the booster. The truck I pulled my engine from was hydro boost

Found it
The dealership wont sell me just the valve for a 2003 Tahoe, they say it only comes with the booster.

So I went across the street to a Cadillac dealer and asked for a ACDelco 179-1322. This is the valve with the larger 15/32 port on the hose side and fits the booster perfect.
