Ok Grey wolf you confused me???????? I have two holes in the offy intake man. which I plugged off. One hole in the carb spacer with I plugged off. One vac fitting on the dist. which goes to carb. three fittings on carb. One which was the one from the dist. One for PCV valve and the third fitting on the carb I have no clue what it is for. I am in a whole other world when it comes to the vacuum of a vehicle. All I know is that if it leaks it doesnt run right LOL
Like I have said before this is my first build. It was my father's truck
