INSTALLATION

Know and follow applicable national, state and local safety
codes pertaining to installing and operating equipment for
use with petroleum fluids

Make sure the tank is vented to prevent the buildup of pres­sure and possible fuel leakage through the nozzle.

Use the following procedures to install the HP-90 Hand Pump
on a tank with a 2-inch NPT bung.

Install Suction Pipe

1. Place PVC pipe into flared end of PVC pipe assembly.
Use PVC cement if desired. The end of the pipe should
be 2-3 inches above the bottom of the tank, when in­stalled correctly. Cut pipe to fit tank.

2. Remove the two protective plugs from the inlet and outlet
ports.

3. Wrap the threaded end of the suction pipe with 3 to 4
turns of Teflon® tape.

4. Install the suction pipe into the pump inlet and tighten
with a wrench.

Install Pump on Tank

1. Lubricate the male threads on the pump inlet with Teflon
tape or a thread-sealing compound approved for use
with petroleum fuels.

2. Thread the pump onto the tank and turn pump to tighten
securely.

Install Handle

1. Slide the grip onto the pump handle.

2. Install one end of the link in the pump housing, the other
end in the bottom hole in the pump handle. Connect
the pump handle to the shaft with the clevis pin and
secure with the cotter pin.

to extend the life of your hand pump.
