Remote Fuel Pump
The Model OT-250 tank has a platform designed for attaching the
remote fuel pump.
• Attach the fuel pump legs permanently either on the platform,
directly to a field-supplied tank, or in a location very near to
the oil tank.
• Mount the remote pump assembly in an upright, horizontal
position as shown in the illustration. (
NOTE:
Motor enclosure
appearance may be different than illustrated but must always
be mounted in this upright position.)
CAUTION: Do not mount the pump assembly in a
vertical or inverted position.

Supply Lines
Read this section carefully before installing any supply lines. Since a suction line leak is nearly im-
possible to find, take your time to assure all connections are leak-free during installation.
Supply
lines and fittings are furnished by the installer.
See the following illustration for minimum fittings
required. Length of pipe and tubing depends on the installation.
Run the suction line, using 1/2” standard black iron pipe, between
the inlet side of the filter and the foot valve. (Refer to the illustration.)
A fuel line filter with a cleanable strainer, a foot valve, a foot valve
strainer, and a vacuum gauge are provided with the heater. To pre-
vent air from entering the line, do not use union connections. Install
Suction Line (portion
of supply line from
foot valve to pump)
