D'Oh! I suppose I could have finished my thoughts and made the same suggestion! I have a few Offy manifolds with the same bosses for fittings, as well as a few installed by their factory. I have not run a Torker, so I didn't realize they weren't plumbed for vacuum!

I learned something new today!

Q

PS: Ditto on the use of a Torker on the street. They are not the best choice for a street motor.
