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 manifold screws (120).
2.
Rotate the center manifold (113) to the applicable
vertical or horizontal position.
3.
Install the manifold screws (120) and torque to 50–
60 in-lb (5.65–6.78 N•m). See Torque Sequence,
page 29.

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.
