Just did that. Went out and puchased 11" long needle nose pliers and that helped. The one port in particular gave me access problems. What I did was cut a straight piece of a wire coat hanger (10") and threaded the new hose onto it. Then I stuck the exposed end of the wire onto the top of the nipple hole and pushed the hose down and onto the nipple. Worked great, done in 15 minutes and no leaks.
