There are several way to increase pressure. Primary way is to turn the pressure regulator knob in the direction to increase tension on the spring. Pressure regulator is located on the pump (or very neer) and usually has a large spring. Sometimes the spring is hidden under a twist knob.

The tip/nozzle is actually where the pressure is created by restricting the flow of water thru a very small opening. Use a new tip of the same gpm flow that is required by your machine. 18 hp machine has potential for very high pressure and high gallons per minute.
