Sewer hose holder cap modification on T@B 400

I love the built in sewer hose holder on the 400 but I have been concerned about losing the cap that screws on the tube.  So I decided to make a leash.  The supplies cost under $3.  Supplies used were one 6-32 x 3/4" stainless machine screw and 6-32 x 1/4" T-nut.  Basically all that had to be done was to drill a 1/8" hole is the cap, thread the T-nut on the back of the cap and attach a cord with a loose knot so it would spin on the T-nut and not twist the cord.  Then I drilled a hole in the side of the pipe and inserted the other end of the cord and tapped a wooden wedge into the hole to bind the cord in the hole.  Hope you like it.
