Product review (5 stars): It fixed the problem.
Too bad you need to buy the entire hose just to get the nozzle.  Before you install it, watch the YouTube video (Google "4388152 Video").  It was very helpful.  I followed those instructions except when attaching the string to the new tube.  I drilled a small hole a couple of inches from the end.  Then fed the string through the hole and down and out the tube.  Tied a knot in the end of the string so it couldn't be pulled back through the hole.  Then taped it (like it shows on the video).  That way I could pull a little harder on the string without the string coming loose.  Good luck!
