Product Manual

Mechanical Connections
All threaded fuel connections must be sealed with thread
tape or a pipe thread sealing compound approved for
use with petroleum fuels.
Your pump must be mounted on a vented tank. If the
tank is not vented, contact your GPI distributor for the
correct vent cap.
This pump has a built-in check valve to keep the pump
primed. No additional check valve is required on suction
pipes shorter than 15 ft. (4.6 m). Make sure any check
valves or foot valves used are equipped with proper
pressure relief valves.
Your pump is designed to mount directly to a standard
2-inch female tank tting. For the suction pipe, a 1-1/4-
inch galvanized steel pipe cut to length and threaded
on one end may be used. Suction pipe should extend to
within 3 inches of tank bottom. Apply thread tape to the
suction pipe thread and securely tighten the suction pipe
to the pump inlet port.

Your pump is designed for use only with thin viscosity
petroleum fuels such as gasoline (up to 15% alcohol
blends such as E15), diesel fuel (up to 20% biodiesel
blends such as B20) and kerosene. Do not use this pump
for dispensing any uids other than those for which it was
designed. Using the pump with other fuels can damage
components and void the warranty.

How to Use This Manual
The purpose of this manual is to assist you in installing,
operating and maintaining your GPI pump. If you need
additional assistance, contact your GPI dealer or the GPI
Customer Service Department.
The following safety alert symbols are
used in this manual. Obey all safety
messages that follow this symbol to
avoid possible injury or death.
DANGER indicates an
imminently hazardous
situation which, if not
avoided, will result in
death or serious injury.
WARNING indicates a
potentially hazardous
situation which, if not
avoided, could result in
death or serious injury.
CAUTION indicates a
potentially hazardous
situation which, if not
avoided, may result in
minor or moderate injury.
CAUTION used without
the safety alert symbol
indicates a potentially
hazardous situation
which, if not avoided,
may result in property
damage.
There are inherent dangers wherever ammable fuel and
AC electrical sources are in close proximity.
Static electricity as a source of sparking is always a
concern and requires extreme care in the installation and
operation of your entire fuel transfer system.
Additional components such as meters, automatic nozzles
and lters must be listed for use with fuel transfer systems.
The ow of fuel through a hose and nozzle can generate
static electrical charges and dangerous sparking can
result in re or explosion. Hoses and nozzles must be
electrically conductive and bonded to ground.
It is your responsibility to:
• know and follow applicable national, state and local
safety codes pertaining to installing and operating
electrical equipment for use with ammable liquids.
• know and follow all safety precautions when handling
petroleum fuels.
• ensure that all equipment operators have access to
adequate instructions concerning safe operating and
maintenance procedures.
Coverplates protect the operator from moving
parts. Never operate the pump without coverplates
in place. Never apply electric power to the pump
without coverplates in place. Always disconnect
power before repairing or servicing.
