Additional information

This pressure washer pump, part number 317259GS, mounts to the engine and draws water from the supply hose, then increases pressure for cleaning through the high-pressure hose and spray wand.

If your pressure washer has low or no pressure, leaks from the pump housing, or produces inconsistent spray output, the pump may be worn or damaged. Cracks in the housing, oil leakage, or water dripping from seals are common signs that replacement is needed.

Disconnect the spark plug wire on gas models or unplug electric models before starting the repair. Shut off the water supply, relieve system pressure, and disconnect hoses before removing mounting bolts. Install the replacement pump securely and tighten all connections before restoring power and water supply.
