Yep, those are the numbers I was talking about. Explains why the hose you bought from Pelican worked.

Not sure, mine is off an 87 engine but I'll double check before I send it. Can you measure the diameter of connectors and the top hose?

Numbers are: top connection for vacuum hose: .690" (app 5/8") top connection on block 1.095" (app 1 1/8") bottom connection for block is 1.275" (app 1 1/4"). I know I need to get a mm mic, but right now that is what I have.
