The Honda 78104-YF4-612 Outlet Pipe is a genuine OEM replacement designed for the WN30 water pump. As an authentic Honda part, it is manufactured to the exact specifications of the original, ensuring a proper fit with no guesswork or adaptation. This Outlet Pipe is the correct replacement for WN30 units that need a damaged, cracked, or worn discharge pipe restored to working order.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Outlet Pipe matches the original in dimensions and material, so the pump's discharge connection seals and performs as intended
- Direct-Fit Replacement — designed specifically for the WN30 water pump, this part drops into the original outlet position without rework or modification
- Serial Number Awareness — Honda updates parts at production breaks, so confirm your WN30's serial number against the fitment table before ordering to ensure part number 78104-YF4-612 is correct for your unit
- Restored Discharge Integrity — a cracked or damaged outlet pipe causes flow loss and pressure drop at the pump's discharge port; replacing it with this OEM pipe restores full output to the line
The outlet pipe carries water from the pump's discharge port to the connected hose or piping system, forming the final transition point between the pump body and the delivery line. A properly seated outlet pipe maintains the pressure and flow rate the WN30 is rated to deliver. When this pipe cracks, corrodes, or its sealing surfaces deteriorate, the pump loses efficiency and can allow water to escape at the connection point rather than reaching the intended destination.
