I'm not sure why there are so many negative reviews of this item. It works as intended if you are using it for the correct application. This is intended for moving your air hose chuck to a remote location, not as a direct install on the air compressor or manifold. I used a standard air hose and some fittings from a hardware store that I had purchased before I bought this kit and mounted it to an aluminum plate behind my front grill on my ‘21 Tacoma.
