The Honda 78104-954-670 Pump Outlet Pipe is a genuine OEM component designed for the WA20 water pump. As a direct Honda OEM part, it is manufactured to the exact specifications of the original, ensuring a proper connection and consistent flow performance in your pump's discharge circuit. Verify your unit's serial number against the fitment table before ordering to confirm this is the correct pipe for your WA20.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this pipe is built to the same specification as the original, ensuring consistent discharge performance without improvised fitting.
- Exact-Match Outlet Connection — engineered to seat precisely at the pump's discharge point, maintaining the correct flow path and sealing integrity that an off-spec pipe cannot guarantee.
- Designed for the WA20 Water Pump — this part is specific to the WA20; confirm your serial number against the fitment table to ensure you have the correct outlet pipe for your unit.
The Pump Outlet Pipe is the discharge conduit through which water exits the pump after passing through the impeller and volute of the WA20 centrifugal water pump. It channels pressurized flow from the pump body to the hose or piping at the outlet side of the system, and its geometry and sealing surfaces are matched to the pump housing. A cracked, corroded, or poorly fitted outlet pipe will cause pressure loss, leakage at the discharge connection, and reduced pumping capacity — issues that a correctly fitted OEM replacement resolves at the source.
