Hey y'all, You guys always have great advice. It seems like several of you always hit the mark. With that said, can some one advise me on my missing vacuum line to the diaphram that closes the butterfly plate to pull cold air across the exhaust manifold on winter start ups. When I got the truck some lines were gone and some unplugged electrical under the hood. The truck runs basically good. Does anyone one know where the vac line runs to from the aircleaner??
