This is an OEM detergent suction kit, also referred to as a chemical injection kit, for a pressure washer. This kit is threaded into the pump assembly and is connected to the chemical siphon tube that is located in a container that holds the cleaner. This kit includes, (1) bronze nozzle, (1) large O-ring, (1) small O-ring, (1) steel ball, (1) spring (5 components total). For this repair, use a pair of pliers to grasp the detergent supply tube and remove the tube from the chemical injector. Remove the old injector with a wrench. To prepare the kit, start by placing the O-rings on the bronzed nozzle, then the steel ball, then the spring. Apply lubricant on the large O-ring and then thread it back into the port.
