[Fit on] 190593GS Chemical Injector Kit is a replacement soap injector kit for various pump models, compatible with many FAIP Pumps and Himore Pumps, including Husky, Task Force, and Faip models. [Function] If the chemical injector on your pressure washer is worn out, rusted, or clogged due to hard water deposits, this kit can be used as a replacement. [Easy Installation] To replace: Follow the soap hose to the end to locate the injector. Use a wrench to remove the old injector. Clean any residue or dried soap from the receptacle. Ensure the rubber O-ring is in place on the injector. Insert the ball bearing into the injector, then add the spring with the smaller end facing the ball bearing. Insert the assembly into the receptacle and tighten using a 13mm wrench. Do not overtighten, as this may damage the O-ring or crack the pump housing. Note: Installation guide not included. Professional installation is recommended. Please verify compatibility before purchase. Tips: Product design may vary slightly between batches.
