Helm steers indefinitely in either direction after installing the 2.1L pump for a GHP 10 autopilot

Older versions of the 2.1L pump (010-11099-00) include integrated relief valves to protect the helm and cylinder from excessive pressure. On some power assist installations, the helm pressure exceeds the relief pressure, so the valves will allow fluid to circulate even after the cylinder reaches the hydraulic stop. The cylinder will immediately start moving again when the direction of helm movement is reversed, so there should be no adverse affects on boat steering.

NOTE: Newer versions of the 2.1L pump (010-11099-10) will not have this issue.
