Will this pump fit my pressure washer?

It fits matching gas pressure washers with a 3/4-inch horizontal engine shaft. Fit also depends on the mounting pattern, inlet and outlet direction, and available frame clearance; a brand name or PSI rating alone does not determine fit.

Is this a horizontal or vertical pressure washer pump?

This is a horizontal axial replacement pump. It is not designed for vertical-shaft engines, 7/8-inch shafts, 1-inch shafts, or electric pressure washers.

Can this pump be used with hot water?

No. These pumps are for cold-water use only. A thermal relief valve helps protect the pump from heat buildup during operation; it does not make the pump suitable for a hot-water pressure washer system.

Why is there low or no pressure after installation?

Check the water supply, trapped air, nozzle, and hose connections. Ensure proper engine-pump compatibility. For leaks, inspect fittings and seals. Low pressure doesn't always indicate a faulty pump.

How do I identify a 3/4-inch horizontal shaft?

With the old pump removed, the engine output shaft should extend horizontally, parallel to the ground. A 3/4-inch shaft measures 0.75 inch in diameter. The mounting pattern and frame clearance must also match.
