Review on 🚂 Powerful Kleinn Air Horns GMTRK-1 Bolt-On Train Horn for Enhanced Safety & Attention-Grabbing Sounds by Justin Miller

My photo is the schematic I used when hooking it up. The instructions are not as clear as they should be. Watch the YouTube video ahead of time to get an idea of where the journey is headed. I rate it about 4 1/2 stars. First, the 1/2-28 threaded bolts included in the kit to attach the compressor and tank to your vehicle's battery box are too short. Buy 3 inch screws. The second problem I had was that one of the horns was leaking air and I had to take it apart and re-tape the threads with teflon tape. Now everything is in order. The installation will take some time. 3-6 days I added a tee with a short piece of rubber air tubing and then attached a small ball valve to drain the water from the tank. I also added a pressure gauge to the same T-connector so I know it inflates the tank to 140 PSI. I also added a switch that comes out of the ignition wire, in case of an air leak the compressor won't run all the time while the road is on. Also make sure the line in the tank is clean. Take a deep breath. If you can't breathe deeply, it takes a few minutes for the compressor to fill with air. One last thought, I used a lighter and heated up the plastic air hoses so I can squeeze them against the fittings. If you don't, I don't think you'll get lines. This is a good kit, but it is very slow to assemble. Every car will have obs. or 3 to treat or an older car has rust that slows assembly. I recommend the kit, but it's not as easy to assemble as advertised.
