DESCRIPTION
The Simplex Fuel Supply
System provided on this
work order consists of
a Simplex Smart-Pump
designed to transfer fuel
from gravity trucks to an
above ground fuel stor-
age tank, control the fi ll-
ing operation to prevent

allow for full draining of
the truck delivery hose.
A fl oatswitch assembly is
shipped loose for installa-
tion on the above ground
fuel storage tank.

corner of left-hand side panel. Con-
nect ground wires from SmartPump

Part of Typical Piping Diagram
ALL PIPING MUST RISE ABOVE
THE SMARTPUMP. Low spots
can cause air locks in the line
and prevent proper pump op-
eration.
To prevent an accidental spill
due to siphon backfl ow the tank
must have drop tube with an
anti-siphon bleed hole.
