How expensive is the kit that is shown in the video? I would love to have one to simplify my life, however, I don't want to break my piggy bank to pieces to buy it. I have been struggling with getting the correct fittings to fit my hoses to put new couplings onto them. I just bought 3 pairs on Amazon from Summit to try to find what fits. I know that one hose is NPTM one is O ring, and the 3rd looks like it is JIC because it has a flare at the end of the threads, but when I took the old coupling to the NAPA store, they said it wasn't. They couldn't figure it out either and that one will have to wait until I can figure out what it is.
