Fire could result.
• A filter should be used on pump outlet to ensure that no foreign material is transferred to fuel
tank.
• Use fuel-resistant thread sealant or sealant tape on all threaded joints to protect against leakage.
• Storage tank or barrel should be anchored to prevent tipping in both the full and empty conditions.
• To minimize static electricity build-up, keep nozzle in contact with container being filled.
INSTALLATION
Use the following procedures to install the hand fuel pump on a tank with a 2in. bung.
Install suction pipe
1. Remove the two protective plugs from the pump inlet and outlet ports.
2. Wrap the threaded end of the suction pipe with 3 to 4 turns of Teflon tape.
3. Install the suction pipe into the inlet cover and tighten firmly with a pipe wrench.
Install handle
1. To install the links on the pump, insert a long clevis pin through the link ends and the pump’s
link holes. Secure with a small cotter pin. (Figure 1)
2. Attach the free ends of the links to the bottom, outer surfaces of the handle. Insert a long
clevis pin through the holes on both links and the lowest hole on the handle. Secure with a
small cotter pin. (Figure 2)
3. Insert a screwdriver in the piston shaft of the pump and pull the piston out. Install the shaft
on the handle at either piston hole by placing a short clevis pin through the handle and the
piston shaft end and securing with the hitch clip pin.

Install pump on tank
1. Before installing the pump, clean the tank interior of all dirt and foreign material.
2. Lubricate the threads of the inlet cover with Teflon tape or a thread-sealing compound
approved for use with petroleum fuels.
3. Extend the adjustable suction pipe to its full length and carefully insert it into tank opening.
The suction pipe will adjust to the length needed and rest on the bottom of tank.
NOTE: The suction pipe supplied has a variable length of 22 to 40 inches. If additional
length is needed, order the 15-inch Suction Pipe Extension Kit.
4. Thread the inlet fitting of the pump onto the tank and turn the pump to tighten snugly.
NOTE: To prevent the buildup of pressure and possible fuel leakage through the nozzle,
make sure the tank is vented.
Install hose and nozzle assembly
Apply 3 to 4 wraps of Teflon tape to the threaded end of the hose and hand-tighten into the
outlet cover until snug.
OPERATION INSTRUCTIONS
