They are on OEMY's web site. However, I initially bought the NAPA hoses and didn't like the fit. I returned them and bought the upper and lower hoses from Ultra RV Products and they were OEM Workhorse and fit perfectly. I bought the bypass hose from a local Chevy dealer since it's a GM part number. I bought NAPA's best heater hose and also replaced the heater valve while it was apart.
