Pressure washer replacement pump restores strong, consistent water pressure so you can get back to fast outdoor cleaning without replacing the whole machine. Built for 7/8 in vertical shaft engines with a standard SAE bolt pattern, it delivers up to 3100 PSI and 2.5 GPM for driveways, siding, fences, and vehicles. Cast aluminum construction supports reliable performance, while the maintenance-free crankcase eliminates oil changes.

When your washer loses pressure, surges, or won’t build consistent output, a replacement pump is often the fastest fix. This kit is designed for quick swap-in compatibility with common vertical-shaft gas engine configurations and includes the accessories needed to dial in spray patterns and keep tips clear. Confirm your shaft diameter and inlet/outlet connections before ordering to ensure a smooth install. Grab yours today and put your pressure washer back to work.
