Bolted right up to the motor. This thing has plenty of pressure. If I try and crank up the pressure to the max it will bog the motor. So I simply backed it off a little. My only complaint is after a few minutes of use, it will get air pockets and I almost have to prime it again, turning off the motor and pulling the trigger of the wand for a second and then starting it again. After doing this once it will work flawlessly until I’m done using it. Overall good value for the price considering the cost of the original pump.
