Orientation of Fluid Inlet and
Outlet Ports
The fluid port of the center manifold can be rotated to
either a vertical or horizontal position.
To change the fluid port orientation of the center
manifold (113):
1. Remove the clevis and cotter pins (126, 127).
2. Rotate the center manifold (113) to the applicable
vertical or horizontal position.
3. Install the clevis and cotter pins (126, 127).

Some systems may require installation of a pressure
relief valve (V) at the pump outlet to prevent
overpressurization and rupture of the pump or hose.
Thermal expansion of fluid in the outlet line can
cause overpressurization. Thermal expansion can
occur when using long fluid lines exposed to sunlight
or ambient heat, or when pumping from a cool to a
warm area (for example, from an underground tank).
Overpressurization also can occur if the pump is
used to feed fluid to a piston pump, and the intake
valve of the piston pump does not close, causing
fluid to back up in the outlet line.
The pressure relief valve reduces the risk of serious
injury, including splashing in the eyes or on the skin.
