Vacuum source in the Revmaster engine
Luis,
I am flying the Revmaster, but I do not use a vacuum drive instrument. I do
have a Dynon D6. A good solution for sure. Like John mentioned, check for room
before you install, mine is tight but worked out.
Thanks,

I see Spruce has three sizes of venturi tubes available. If it's only
going to drive one instrument that would be a simple and inexpensive
solution.

I had a 1983 Cadillac with the 4.1 V-8 that had a belt driven vacuum pump
