okay here the deal, my friend's 1978 fairmont has a 302 in it, and its running like crap. today we replaced the soleiniod and starter and a vacuum hose come off. it comes from the drivers-side vavle cover and goes somewhere, which i have no idea where it goes. half the emissions on it aren't even hooked up. it has a 2 barrel carb on a 302 block. help would be great.
