Anyone have a p/n for this hydraulic pressure switch...

The purpose of the 50 PSI switch is to allow the pump to build pressure BEFORE the solenoid valves open. It is split second operation but needed. If the system did not have the 3000 PSI pump pressure and you had some jacks extended and wanted to extend some jacks, the jacks extended would drop(retract) slightly due to the momentary pressure loss. Hence, the 50 PSI switch. SO, it is not a good idea to bypass it. Doug
