Depending on engine configuration, longer bolts and spacers (washers) may be needed to mount the pump properly—especially if the engine has a longer shaft or the pump legs hit the frame or engine. Failure to use spacers when needed can cause pump legs to break from stress. Spacers and longer bolts are not included but can be purchased at a hardware store. Common bolt sizes: (2) 5/16-18 x 2-1/2, and (1) 5/16-18 x 3-1/2 This pump mounts vertical and is a front facing (water inlets/outlets come out of the front of the engine). Pump needs at least 6HP to handle PSI. Pump head can be flipped. Thermal relief valve comes pre-installed. This is a sealed unit, no oil maintenance required. Please note it is not recommended to run any pressure washer pump above its maximum PSI rating. Doing so can result in damage to the pump (not covered by warranty) and/or serious bodily injury
