Overview

The Viper VV3G36-FP is a fully plumbed direct-drive replacement pump rated 3 GPM at 3600 PSI, built for gas pressure washers running a Honda GX270 or GX340 (9–11 HP engines with a 1" shaft). Because it comes fully plumbed — VRT3-310EZ unloader/regulator, water inlet fitting with filter, easy start valve, thermo valve, and pump oil all installed — there's no piecing together plumbing from your old pump: bolt it to the engine shaft, set your pressure, and you're back to work. It runs at 3400 RPM in a direct-drive configuration, making it a straightforward swap for a worn or blown pump on a 9–11 HP cold-water machine.

Frequently asked questions

It fits Honda GX270 and GX340 engines — 9–11 HP gas engines with a 1" horizontal shaft. It's a direct-drive pump, so it bolts straight onto the engine shaft. Confirm your engine has a 1" shaft before ordering; smaller-shaft engines need a different pump.

The package includes the VV3G36G pump fully plumbed with a VRT3-310EZ unloader/regulator, water inlet fitting with filter, easy start valve, thermo valve, and pump oil. Everything is pre-installed — mount the pump, set the pressure, and you're ready to run.

No — the VRT3-310EZ unloader/regulator comes installed on this fully plumbed pump. Note that all pumps still require a secondary pressure safety relief device (a pop-off or safety valve) in the system in addition to the unloader; running without one risks injury and pump damage.

Fully plumbed means the unloader, inlet fitting with filter, easy start valve, and thermo valve are already mounted and connected on the pump. You don't transfer plumbing from your old pump or assemble components — bolt it to the engine, set your pressure, and go.
