I had this on my 02 FX4 150 and decided to sell it for some more cash dollars to throw at my cobra rebuild. It includes the duel horn setup about 20 or so feet of tubing and the tank. I didnt have a pump or compressor, I just filled it up at the gas station before I went anywhere. I put anywhere from 100-125 PSI in the tank at a time. a good horn blast took between 5 and 10 psi. Its hilarious to scare people with. VERY LOUD!!! I would like to get $75 bucks for everything if its local pickup. I can do $90 shipped anywhere in the country. Its a pretty big tank and the horn alone is prolly worth 75. I have a second horn, thats IH brand, the chrome is pretty beat up tho.... text for quicker response 419-689-3648
