Flange Configuration
WARNING! Be certain seals and screen are properly positioned and clean any time the flanges are
reconfigured. Improperly installed or dirty seals or screens could cause leaks and the potential for fire or
explosion
CAUTION! Always be certain the power switch is accessible after reconfiguring the inlet and outlet ports.
The inlet and outlet flanges of your RD series pump can be configured vertically, horizontally, or a combination of both.
To change the position of a flange:
1. Remove the two socket head cap bolts holding the flange in position.
2. Remove the flange; examine the sealing surfaces to be certain they are clean and will seal properly.
3. Position the seal and screen, and place the flange in the desired position.
4. Use the two socket head cap bolts to reattach the flange firmly to the pump housing. Torque to 50 inch lbs. with a 4
mm hex key.

DC Power Connection
DANGER! Be certain the power switch is "OFF" prior to connecting the battery clamps / power cables to the
power source or installing the cable into the pump to prevent unexpected starting of the motor. Unexpected
motor start can cause unintended discharge of fuel, creating an explosion and fire hazard.
Inspect power cable before each use! Damage to the
outer jacket of the cable that exposes wiring requires
replacement of the power cable.
Install power cable by aligning flat on plug with front of
pump. Insert the plug into the pump housing as shown.
Lock into place using the threaded collar (A). HAND
TIGHTEN ONLY! The power cable terminates in green,
black, and red clamps. All three clamps must be used.
1. The green (ground) clamp should be connected first.
Connect the green clamp to the vehicle chassis or
earth ground. DO NOT connect the green clamp to the
negative power source post.
2. Next, connect the black (negative) clamp to the
negative post of the DC power source.
3. Connect the red (positive) clamp to the positive post
last.
Clamps should be disconnected in reverse order.
