I want to replace the stock air cleaner "box" on my buick 307 V8 with a nice chrome open element filter. I noticed that inside where the filter sits has a little sensor witha vacuum line that goes to some sort of valve that sits next to the carb. Can i just plug the hole in the valve where and toss the hose along with the sensor away? What about the hose(about 1" diameter) that comes out on the passenger side and goes to what looks to be an air pump? What do i do with that? and last, what about the heat riser valve that in the intake tube, just toss that too?
