Tested Pump Kit Showdown: 3400 PSI Power and Siphon Tube... Best for Gas Washers In our recent exploration of replacement pressure washer pump kits, the OEM Technologies 90029 stood out for its robust performance and thoughtful inclusion details. We were particularly impressed with the 3400 PSI, 2.5 GPM output, which delivers the kind of power needed for both residential and industrial gas-powered machines. The 3/4-inch shaft fit was seamless, and we appreciated the inclusion of hardware and a siphon tube—a small yet crucial addition that saved us time and hassle. The build quality felt beefy, suggesting longevity, while the straightforward installation process meant we were back up and running in no time. While we've tested others, this kit’s combination of strength, convenience, and affordability makes it a standout choice for gas washer users like us.
