Redline Detection, LLC introduces the Smoke Pro Universal Filler Neck Connector to the global automotive aftermarket. The Universal Filler Neck Connector is a brand new product that can be used in conjunction with Redline's "Smoke Pro," the world's best-selling smoke machine, to quickly locate and repair even the smallest of leaks in any sealed vehicle system. The Smoke Pro functions by precisely pressurizing smoke into one of the car's sealed systems, which produces tell-tale smoke and pin-points the location of the leak.
