Anyone know the size of the thread/pitch of the vacuum fitting that screws into the manifold just in front of the carb. The one with two small vac lines coming out. It seems to be the same as the diff. breather, which is close enough to 1/8th" NPT for practical purposes.
#2 The intake manifold is aluminum, correct? If so, is it like steel in that it is harder than brass so brass fittings will give way, or is it soft enough where I had better not try?
#3 If I cannot use brass NPT fittings in the intake manifold, is there a safe was to get a single fitting for 1/4" ID hose using that tapped hole in the intake manifold? (without drilling out to accept 1/4" NPT)
Thanks.
