RP-10 Rotary Hand Pump
for Fuel and Petroleum

Owner’s Manual

GENERAL INFORMATION

The RP-10 Rotary Hand pump is designed for use with gasoline
(up to 15% alcohol blends such as E15), diesel fuel (up to 20%
bio-diesel blends such as B20), kerosene and up to medium
weight oils. These self-priming pumps deliver up to 10 gallons
(38 litres) per 100 revolutions and are designed for use on a tank
with a 2-inch bung. They are equipped with an anti-siphon vent
to prevent possible tank siphoning. Do not use the RP-10 pump
with chemicals.

Safety Instructions

Observe standard safety precautions when handling fuel.

• Keep away from open flame or spark.

• Do not refuel vehicles or equipment with engines running or
while equipment engine is hot.

•

Do not smoke while refueling.

Before installation, clean the tank interior of dirt and foreign mate­rial. Wrap all threads that are exposed to liquids with 3 to 4 turns of
Teflon
petroleum fuels. Remove protective covers and plugs.

INSTALLATION

1. Hand-tighten the riser on to the tank bung.

2. Assemble the crank and handle. Then snugly tighten the crank on­to the shaft. Reference the Illustrated Parts Drawing for details.

. Screw the suction pipe into the pump inlet.

3

4. Extend the suction pipe to its full length. Insert it through the
riser and into the tank. Adjust the suction pipe to the length
needed to rest on the tank bottom. If tank debris is a potential
problem, raise the end of the suction pipe 2 to 3 inches.

5

. Secure the pump onto the riser with the two set screws. Tighten

until snug.

To install the hose and nozzle, thread the elbow fitting into the
pump outlet and tighten until snug. Hand-tighten the hose into the
elbow until snug. Tighten the nozzle onto the hose fitting. Insert
the nozzle into the hanger.

OPERATIONS

To dispense fuel, remove the nozzle from its hanger and insert into
a tank. Pump fuel by rotating the crank in the direction of the ar­row on the housing. After dis­pensing fuel, drain the hose
and replace the nozzle in the
hanger.

During daily use, this pump is
essentially maintenance free.
However, the pump should be
inspected periodically for signs
of leakage. If leaks are present or
other problems occur, refer to the
Troubleshooting Section.
