Sizing a kunkle valve

[ThaBeast]

I have a sutorbilt 4lp blower, which according to Gardner Denver should be run at a max of 14" hg. So I was thinking my vac relief should be set at 13" hg. Any input?

Would like to make sure I don't trash a brand new blower.

I would set it at 14 and not worry. The manufacture has already caluclated the safety factor.

Are you trying to figure which one to buy or where to adjust it? BTW if you are buying, get a Bayco, not a Kunkle.

Take care,
