Yes to 1 connection point; intake manifold to carb. Or valve cover to carb? Largest carb vac. point 5/16" or 3/8", haven't measured yet.
On second thought, I'm going w/pcv hook up from valve cover to carb 1st. Will install non breathing
oil filler cap & test. Leaving only the rear intake breather & breather on puke tank. Will report back in few days when weather clears.
Thanks again.
