Sick and tired of having to get under your vehicle to drain your tank? Or maybe you’re just building the ultimate system and want the best of the best. Either way, this is a must have upgrade to any train horn kit!

Once installed, you’ll be able to drain the moisture in your tank at the touch of a button. Sounds like some chore to perform? Trust us, its not. In fact, the air discharge from the valve has been known to turn heads by itself! You have to do it anyway, so why not make your life easier?
