The components of a hydraulic steering system start with the steering ram. Selecting a quality ram is important because of the load it carries. Brass, bronze, and stainless steel are the only materials that are acceptable in the construction of any ram. With hydraulic power steering, a 2nd pump is driven by another motor, either your engine or a small electric motor. In most cases with power steering, you have fewer turns lock to lock, and less steering effort. Looking to upgrade system components use of SAE or JIC flare fittings with copper, metallic tubing, pipe matted with a reinforced non-metallic hose.
