39' MM GT Vaccum Questions

d21smith · Feb 20, 2013

Hello guys im putting my gt back together from rebuilding and when i got the tractor the manifold was off of the tractor, well now that im about ready to install it after brazing a crack in it ive found that it has two fittings coming out of the intake manifold and i do not know where they are supposed to go i would assume they are vaccume lines? they are not primer cup locations because they are on the bottom side of the manifold not the top, one is on the bottom left side as you are looking at the manifold and the other is in the center with a large fitting and a 90 degree elbow? any help is appreciated, thank you.

I say plug them. Most all tractors of that era had these access to vacuum ports. I've heard that they were used for milking machines? Anyway, assuming the tractor is not an LP gas burner, those ports serve no purpose other than testing as far as I know.
