Query: Do not buy this fro K 3.690 washer

DO NOT BUY THIS PART if you own a K 3.690. IT DOES NOT FIT. I looked up the part number on the Karcher web site which same as what is listed here and drove to local Walmart and bought the hose only to find the connectors are totally wrong! I have the newer model K 3.690 with the built in reel.
