I installed this in my Ford truck along the chassis frame and made a small aluminum screen to keep road salt, sand and water out of the compressor. The tank holds air pressure well. put 4 horns in front of my radiator. When I first bought the kit it only came with a cheap compressor and never had the right power to blow the horn. after two compressor changes i switched to this system. best move since buying a horn replacement. Now I have the strength I need when I need it. I can also use the tank with a set of air hoses to inflate tires wherever I am. good product
