Holley 94 vacuum port plug
I am looking for a source for the vacuum port plug that fits the Holley 94 carb. It appears to be an odd size / thread type. Any one have any info that might help me locate them?

Re: Holley 94 vacuum port plug
SAE 45degree flare plug fits there...Eaton has them or any major supplier of brass fittings.
Thread is UNF if i got it right so not exotic... |

Re: Holley 94 vacuum port plug
When I had to plug them, I always used a "Ford Nut" soldered up. Are you telling me a 3/8-24 set screw would have saved those rare pieces?

Re: Holley 94 vacuum port plug
Sal, does it need to be a ferrule type thread?

Re: Holley 94 vacuum port plug
Answer to my last question was no based on small amount of vacuum being plugged.
