Installation
Choose a mounting location which provides accessibility to the end plate of the pump, in order to facilitate future impeller changes, and provides a hose run under ten feet. Mount the pump by drilling four holes corresponding to the holes in the base plate. The pump head has ports on either side which can be used interchangeably as the supply or discharge, as the motor is reversible. The ports are externally threaded with 3/4" hose threads and internally threaded with 3/8" pipe thread. 1/2" or 5/8" hose is recommended for connection to the engine; smaller hose is not recommended. Choose fittings which fit the hose size selected. We carry a full line of hose fittings and pan fittings for most engines.

Electrical Connection
Use a minimum #14 gauge wire to connect the pump. Connect the positive lead to the orange or red wire and connect the common lead to the black wire. If a circuit breaker is to be installed in the circuit, use a 20 amp breaker as the start-up load will cause a smaller circuit breaker to trip.

System Priming
To avoid unnecessary wear on the impeller do not run it dry. It is necessary to prime the pump with oil before initial use.
1. Pour a small amount of oil (3 oz) into the fill/ discharge hose. Allow this oil to run into the pump head
2. Place the fill/ discharge hose in a container of new oil.
3. Operate the pump for a few seconds to draw oil into this line. Once the system is primed, this procedure does not have to be repeated again. The residual oil in the line is sufficient to lubricate the impeller for subsequent oil changes.
