The 90036 features a stainless steel integrated unloader featuring our easy-start system. (*Check your pressure washer's inlet and outlet orientation to ensure compatibility)

Review: Direct replacement - Mounted right up and worked fantastic. Pressure was slightly higher than the original. Nice replacement part.
Review: The pump will fail with out water. - I purchased this to replace the original pump on my Simpson pressure washer which was almost new. The pump works great and is the same as on the original pressure washer. I would caution that the pump works great as long as the water is turned on. The pump is of a very good quality but has plastic valves - if the water stops the pump heats up very quickly and the plastic valves just melt and the pump no longer functions. This was my experience - the water stopped and the valves melted. I purchased the entire pump since just the valve portion was not available.

## Features

- Compatibility: SAE standard bolt pattern fits many gas pressure washers with horizontal engines. To ensure compatibility, be sure to match engine orientation, PSI, GPM, engine shaft diameter, and current pump inlet and outlet connection

*by D***E on September 10, 2020*

I purchased this to replace the original pump on my Simpson pressure washer which was almost new. The pump works great and is the same as on the original pressure washer. I would caution that the pump works great as long as the water is turned on.

### ⭐⭐⭐⭐ Great stereo sound. Excellent. Had it 3 weeks.
*by A***U on December 15, 2025*

I am very happy with the bluetooth so far. Had it for 3 weeks. It alerts when you walk away from your phone when connected. It warns low battery. Great stereo sound. I wish it had a last number call back feature. USB port is at top. If this comes loose, or open, rain might enter.
