I am trying to replace the lower radiator hose on my Midget. It is a downflow radiator. I got the old hose off but I have been trying to get the new one on for almost an hour. There is hardly any clearance on the bottom fitting so I can't get my hand on the hose enough to push it on. The top fitting just doesn't want to go on the water pump. Does anyone have any suggestions on how to get them on?
