Mine isn't holding any vacuum and needs replaced.
I saw a post by Lars saying this:
If you're running a little bit of a cam, order part number VC1810.
But I don't think they make it anymore.
Any suggestions on which one to purchase?
HEI with a big cam with 7-8Hg and can get up to 10Hg messing with timing.
I prefer Summit or oriellys numbers if they have them.
Unobtanium......looks like they have been out of production since 2009.......even any part number that crosses....the GM# is 88924985. All you can do is try the VC1809 or get an adjustable one.......the Accel unit has the ability to do what you want....

One more piece of advice - Check whichever one you end up with a MightyVac to make sure it has the proper specs. I’ve been hearing stories of people buying them and they have been way off.
