The relief valve for setting up the pressure is in the main control valve for the lift control. It takes shims, and more shims are added to increase the spring tension. The more spring tension, the more pressure. But if your system has gotten weaker and slower over time, the hydraulic pump might be the problem. And adding more shims to raise pressure will do nothing.
