Pressure Relief Valve (Fuel Dispense
Systems)
Changing the Orientation of the Fluid Inlet
and Outlet Ports
If desired, you can easily change the orientation of the
fluid inlet and outlet ports. See Fig. 6.
1.
Remove the screws (6) holding the inlet and/or outlet
manifold (1, 3) to the covers (2).
2.
Reverse the manifold and reattach. Install the screws
and torque to 120 to 150 in–lb (14–17 N•m). See
Torque Sequence on page 25.

Pressure relief valve (required to limit
fluid outlet pressure to 50 psi [350
kPa, 3.5 bar])
Fluid from the relief valve (46) must
be vented to a safe area.

Fuel Dispense System
WARNING
Fuel Dispense Model 810.0781 requires a pressure
relief valve 819.0252 (46), which is supplied with the
pump, to prevent fluid pressure from exceeding 50 psi
(350 kPa, 3.5 bar). Do not exceed the maximum air inlet
pressure of 50 psi (350 kPa, 3.5 bar). Recommended air
operating pressure is 40 psi (280 kPa, 2.8 bar) or less.
As the air inlet pressure approaches 50 psi (350 kPa, 3.5
bar), the relief valve will open and vent fluid. Vented fluid
must be routed to a container in a safe place.
