Mechanical Connections
NOTE: All threaded fuel connections must be sealed with thread tape or a
pipe thread sealing compound approved for use with petroleum fuels and
tightened securely to prevent leakage.
NOTE: This pump must be mounted on a vented tank.
NOTE: This pump is designed to mount directly to a standard 2 in. male
pump tank mount adapter (included).
NOTE: This pump is designed to self-prime with dry gears.
If you require a greater initial prime height, coat the gears with fluid by
removing the outlet fitting on the top of the pump and pour a small quantity
of motor oil into the gear cavity. Replace and try again. A foot valve with
pressure relief may be needed to maintain prime.
Install Tank Adapter and Suction Pipe
1. Wrap lower threaded end of the tank adapter with three or four turns of
thread tape (see Figure 2). Using a wrench, tighten the adapter snugly into
the fuel tank.
NOTE: For Aluminum Tank Installation - To prevent thread galling of
aluminum fittings, always prepare the threads for assembly using an
anti-seize compound such as Loctite® 567™, Hernon® Dripstop® 940 or
equivalent.
2. Using pliers, remove the plastic plug from inlet port on bottom of pump.
Place the spin collar gasket into the inlet fitting on the bottom of the
pump.
3. Wrap the threaded end of suction pipe with three or four turns of thread
tape (see Figure 3). Thread the suction pipe into the inlet port on the
bottom of the pump and hand tighten until snug.
NOTE: If your tank is 15” - 24” deep, do not use the included suction pipe
extension; if your tank is 24” - 40” deep, attach the suction pipe extension
(see Figure 4).
