ok, I went out and looked again, the hose that is lose coming off of the filter is supposed to be going to a 3 way and to the dashpot control valve. where is it supossed to go is plugged by a screw, so I have no idea why that was done. Hose that is lost is thick and covered with red nylon threading of some type. Hopefully I will be able to see what is going on with the engine running.
