Engine vacuum

[KAWMAN2]

can you eliminate the vacuum ball for the a/c door and go strait to manifold vacuum?

No. Longer answer is, the ball is the reserve you’ll need when climbing a hill with the AC on. No ball, door closes half way up the hill and ain’t no one happy with no air.

No hills in Florida, I bypassed the ball and ran it hard today’s/c worked fine, but I will teplace the check valve and ball
