Hi Justin, Thank you for your question. If your pressure washer is leaking water in the oil pump, you will need to replace oil seals in the piston guide. If you need help placing an order for it, customer service is open 7 days a week and anyone will be happy to assist you. Please feel free to give us a call. We look forward to hearing from you!
