The Honda 78151-YB7-711 Suction Hose (4.5M) is a genuine OEM suction hose designed for WA20, WB20, WD20, WD30, WH15, and WH20 water pumps. As a direct OEM replacement, this suction hose meets Honda's original design specifications, giving you confidence that it will connect and perform the way it was intended to from day one. Honda supersedes parts at serial breaks, so confirm your pump's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, so the hose dimensions, fittings, and flexibility match what your water pump was built around
- 4.5M Suction Length — the 4.5-meter length is a variant specification; verify this matches your pump's original hose before ordering, especially if multiple hose lengths are listed for your model
- Broad Pump Compatibility — fits WA20, WB20, WD20, WD30, WH15, and WH20 Honda water pumps, covering a wide range of Honda's centrifugal pump lineup
- Serial Number Verification Recommended — Honda updates parts across production runs, so cross-check your pump's serial number against the fitment table to confirm this is the correct hose for your unit
The suction hose is the intake line that draws water from the source — a pond, tank, flooded area, or standing water — into the pump's inlet. Without a properly sealed, correctly sized suction hose, the pump cannot develop the vacuum needed to prime and move water efficiently. A cracked, kinked, or deteriorated suction hose causes the pump to lose prime, run dry, or deliver reduced flow, cutting into productivity on the job. Replacing a worn hose with the correct OEM part restores full draw capacity and keeps the pump operating at rated performance.
