The Honda 78103-954-670 Intake Pump Pipe is a genuine OEM component built for the WA20 water pump. As a direct Honda OEM part, it is manufactured to the exact specifications of the original, ensuring a proper fit and consistent inlet performance. This part carries part number 78103-954-670 and is the correct replacement when the original intake pipe is damaged, cracked, or leaking.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Intake Pump Pipe matches the original component in dimensions and connection geometry, ensuring a proper seal at the inlet.
- Correct Inlet Flow Path — a cracked or failing intake pipe allows air ingestion at the inlet, disrupting prime and reducing pumping efficiency; replacing it with this part restores full suction capacity.
- WA20 Fitment — designed specifically for the WA20 water pump; verify your unit's serial number against the fitment table to confirm this is the right pipe for your machine.
The intake pump pipe forms part of the suction side of the WA20 water pump, channeling water from the source into the pump body where the impeller can pressurize and move it through the discharge side. A sound, airtight intake pipe is essential for the pump to maintain its prime — any crack, split, or loose connection on the inlet side will allow air to enter, breaking the suction and causing the pump to lose flow or fail to prime altogether. Replacing a worn or damaged intake pipe promptly keeps the pump operating at its rated capacity.
