Fuel Safety
DANGER
GASOLINE AND GASOLINE VAPORS ARE HIGHLY
FLAMMABLE AND EXPLOSIVE.
Fire or explosion can cause severe burns or death.
Gasoline and gasoline vapors:
–Gasoline is highly flammable and explosive.
–Gasoline can cause a fire or explosion if ignited.
–Gasoline is a liquid fuel but its vapors can ignite.
–Gasoline is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
–Gasoline has a distinctive odor, this will help detect potential
leaks quickly.
–In any petroleum gas fire, flames should not be extinguished
unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of fuel is
not turned OFF, then an explosion hazard could be created.
–Gasoline expands or contracts with ambient temperatures.
Never fill the gasoline tank to full capacity, as gasoline needs
room to expand if temperatures rise.
When adding or removing gasoline:
DO NOT light or smoke cigarettes.
Turn the engine off and let it cool for at least two minutes before
removing the gasoline cap. Loosen the cap slowly to relieve
pressure in the tank.
Only fill or drain gasoline outdoors in a well-ventilated area.
DO NOT pump gasoline directly into the engine at the gas station.
Use an approved container to transfer the fuel to the engine.
DO NOT overfill the gasoline tank.
Always keep gasoline away from sparks, open flames, pilot lights,
heat and other sources of ignition.
When starting the engine:
DO NOT attempt to start a damaged engine.
Make certain that the gasoline cap, air filter, spark plug, fuel lines
and exhaust system are properly in place.
Allow spilled gasoline to evaporate fully before attempting to start
the engine.
Make certain that the water pump is resting firmly on level ground.
When operating the water pump:
DO NOT move or tip the water pump during operation.
DO NOT tip the water pump or allow fuel or oil to spill.
When transporting or servicing the water pump:
Make certain that the fuel valve is in the OFF position, the gasoline
tank is empty.
Disconnect the spark plug wire.
When storing the water pump:
Store away from sparks, open flames, pilot lights, heat and other
sources of ignition.
Do not store water pump or gasoline near furnaces, water heaters,
or any other appliances that produce heat or have automatic
ignitions.
WARNING

requires no additional lubrication for the life of the bearing.

ASSEMBLY
14
NOTICE
The recommended oil type is 10W-30 automotive oil.
If running engine in extreme temperatures, refer to the
following chart for recommended oil type.
1. Place the water pump on a flat, level surface.
2. Remove oil fill cap/dipstick to add oil.
3. Using a funnel, add up to 20.3 fl. oz (600 ml) of oil (included)
and replace oil fill cap/dipstick. DO NOT OVERFILL.
4. Check engine oil level before every use and add as needed.
MAX
OIL DIP STICK
NOTICE
Once oil has been added, a visual check should show oil about
1-2 threads from running out of the fill hole.
If using the dipstick to check oil level, DO NOT screw in the
dipstick while checking.
NOTICE
Check oil often during the break-in period. Refer to the
Maintenance section for recommended service intervals.
CAUTION
The engine is equipped with a low oil shut-off and will stop
when the oil level in the crankcase falls below the threshold
level.
NOTICE
The first 5 hours of run time is the break-in period for the
engine. During the break in period, it is recommended to use
standard automotive, non-synthetic blended oils. After the
break-in period, synthetic oil can be used but is not required.
Adjusting throttle setting will increase/decrease engine speed
helping to seat piston rings. Avoid bogging or lugging the
engine down and avoid prolonged running at constant RPM.
After the 5-hour break-in period, change the oil.
NOTICE
Synthetic oil may be used after the 5 hour initial break-in
period. Using synthetic oil does not decrease the recommended
oil change interval. Full synthetic 5W-30 oil will aid in starting
in cold ambient < 41º F (5º C).

1. Place the water pump on a flat, level surface.
2. Remove the gasoline cap.
3. Slowly add gasoline to the tank. DO NOT OVERFILL. Gasoline
can expand after filling. A minimum of ¼ in. (6.4 mm) of
space left in the tank is required for gasoline expansion,
although more than ¼ in. (6.4 mm) is recommended. Gasoline
can be forced out of the tank as a result of expansion if
overfilled, and can affect the stable running condition of the
water pump. The approximate fuel level is shown on the fuel
gauge on top of the fuel tank.

ASSEMBLY

4. Screw on the gasoline cap and wipe away any spilled fuel.
CAUTION
Use regular unleaded gasoline with a minimum octane rating
of 87 and an ethanol content of less than 10% by volume.
DO NOT light cigarettes or smoke when filling the tank.
DO NOT mix oil and gasoline.
Fill tank to approximately ¼ in. (6.4 mm) below the top of the
tank to allow for gasoline expansion.
DO NOT pump gasoline directly into the water pump at the
pump. Use an approved container to transfer the gasoline to
the water pump.
DO NOT fill tank indoors.
DO NOT fill tank when the engine is running or hot.
DO NOT overfill the tank.
WARNING
Pouring gasoline too fast through the fuel screen may result in
blow back of gasoline at the operator while filling.
NOTICE
Our engines work well with 10% or less ethanol blended
gasoline. When using ethanol-gasoline blends there are some
issues worth noting:
–Ethanol-gasoline blends can absorb more water than
gasoline alone.
–These blends can eventually separate, leaving water or a
watery goo in the tank, fuel valve and carburetor.
–With gravity-fed supplies, the compromised gasoline can
be drawn into the carburetor and cause damage to the
engine and/or potential hazards.
–There are only a few suppliers of fuel stabilizer that are
formulated to work with ethanol-gasoline blends.
–Any damages or hazards caused by using improper
gasoline, improperly stored gasoline, and/or improperly
formulated stabilizers, are not covered by manufacturer’s
warranty.
It is advisable to always shut off the gasoline supply, run the
engine to starvation and drain the tank when the equipment is
not in use for more than 30 days.

DO NOT operate the water pump inside any building, including
garages, basements, crawlspaces and sheds, enclosure
or compartment, including the storage compartment of a
recreational vehicle.
DO NOT allow exhaust fumes to enter a confined area through
windows, doors, vents or other openings.
DANGER
Using an engine indoors CAN KILL YOU IN MINUTES. Engine
exhaust contains carbon monoxide. This is a poison you cannot
see or smell.
NEVER use inside a home or garage, EVEN IF doors and
windows are open.
ONLY use OUTSIDE and far away from windows, doors,
and vents.
Install battery-operated carbon monoxide alarms or plug-in
carbon monoxide alarms with battery back-up according to the
manufacturer’s instructions.
WARNING
Running engines produce heat. Severe burns can occur on
contact. Combustible material can catch fire on contact.
DO NOT touch hot surfaces.
Avoid contact with hot exhaust gases.
Allow equipment to cool before touching.
Maintain at least 3 ft. (91.4 cm) of clearance on all sides to
ensure adequate cooling.
Maintain at least 5 ft. (1.5 m) of clearance from combustible
materials.
Place the water pump on a flat, level surface. The pump should
be placed close to the water level to ensure maximum pump
performance.
Pump output will be affected by the type, length, and size of the
suction and discharge hoses. The pumping height, also known as
the total head, is the distance from the water level to the point of
discharge. As this distance increases, pump output decreases.
The discharge capacity is greater than the suction capacity.
Therefore, it is important that the suction head is less than the
discharge head. The time required to draw water from the source
to the pump (self-priming time) can be decreased by minimizing
the suction head.

Connecting a Hose Kit
NOTICE
Both the inlet and outlet ports are 2 in. (5 cm) NPT. Please
ensure the connectors to the suction and discharge hose are
2 in. (5 cm) NPT threaded.
Connect the Discharge Hose (Blue)
1. Locate (1) of the following: outlet hose adapter (C), gasket (A),
and outlet hose fitting (B) and align for assembly.

2. Thread the assembled connector to the outlet fitting (top of
pump). Locate the blue “outlet” label on the pump.
NOTICE
Make sure the gasket is seated inside before threading the
adapter on.
3. Locate and slide the silver colored hose clamp (marked 52-
55) over the blue outlet hose.
4. Slide the blue discharge hose over the outlet hose fitting.
NOTICE
You may use a small amount of dish soap on the outlet hose
fitting to help ease the outlet hose on the fitting. Work the
soap around the fitting with your finger. Then work the blue
hose on the outlet, by twisting and turning until it’s fully
seated.
5. Slide the hose clamp in place about midway on the outlet
hose adapter as shown. Tighten to 7.4±1.5 lbf-ft (10±2 Nm)
with a 10mm wrench. The hose clamp should be placed
behind the outlet adapter barbs on the smooth part of the
adapter.
Connect the Suction Hose (Green) and Suction Filter
1. Locate the following: cam lock coupler (coupler and fitting
together) (A), 54-57 marked hose clamps (B), Teflon®tape
(C), green suction hose (D) and align for assembly.

2. Cut ties and uncoil the green hose and use some weight to
help straighten the hose out. Best to do this on a warmer day
in the sun.
3. Separate the cam lock coupler and fitting. Align the green
hose to the coupler and mark the locations of the ribs on the
fitting.
4. Mark the second rib on the coupler on the hose.
5. Lay the green hose side by side and place the clamp marked
54-57 in their approximate location.
6. Slide the clamps back and start to assemble the green hose
to cam lock coupler.
7. Insert the cam lock coupler in the green rigid suction hose
until properly seated.
NOTICE
You may use a small amount of dish soap on the cam lock
coupler to help ease the green hose on the fitting. Work the
soap around the coupler with your finger. Then work the
green hose on the fitting, by twisting and turning until it’s fully
seated.
You may need to dip the green suction hose into boiling water
for 1 minute to install the hose as well. This will allow the
material to stretch some while assembling the green hose to
the cam lock coupler.
8. Slide the clamps marked 54-57 over cam lock coupler just
past the marks you made on the hose earlier.

OPERATION

9. Rotate and align the clamp bolts so you have clearance for
the cam levers to lock in place later.
10. Tighten each clamp to 11.1±1.5 lbf-ft (15±2 Nm) with a 10mm
socket and 3/8 in. drive ratchet until the clamp completely
tightens. If you do not have a torque wrench, hand tight then
¼ turn past full tight. This will need to be as tight as you can
make them.
11. Once tightened, visually confirm the hose is raised on the
ribs. This indicates you have it tight.
12. Test connection is tight by twisting coupler in the hose to
make sure it doesn’t turn. If coupling turns, then tighten
clamps further until coupling won’t turn.
13. Wrap the green inlet clockwise with the Teflon®tape provided
with 4 complete wraps.
14. Thread the fitting over the tape and hand tighten. Use either
14 in. Channellock®or a pipe wrench with 2.5 in. (63.5mm)
opening min, hand tight then 1 1/2 turn past full tight. This is
critical to make sure the fitting is tight so you do not have air
leaks.
15. Attach the cam lock coupler to the fitting.
16. Lock in place with the cam levers.

NOTICE
If the cam levers do not clamp down completely, rotate and
align the clamp bolts so you have clearance for the cam levers
to lock. See step 9 earlier.
17. Locate the following: filter (E) and 54-57 marked hose
clamp (F).
E
F
18. Snap the filter pieces together.
19. Place the clamp marked 54-57 on the other end of the green
hose. Attach the strainer to the green suction hose.
NOTICE
You may use a small amount of dish soap on the filter to help
ease the green hose on the filter. Work the soap around the
filter with your finger. Then work the green hose on the filter,
by twisting and turning until it’s fully seated.
20. Slide the clamp just before the end of the green hose.
21. Tighten the clamp to 7.4±1.5 lbf-ft (10±2 Nm) with a 10mm
wrench. If you do not have a torque wrench, hand tight then
¼ turn past full tight.
22. You should have everything connected.
Priming the Pump
NOTICE
DO NOT run the pump dry.
Running the pump dry can destroy the pump seals and will void
the warranty. If the pump was running while dry, stop the engine
and allow it to cool thoroughly before filling the chamber with
water.
NOTICE
Ensure the priming plug is secure before pump operation, if not
secure the priming plug could be ejected and water or other
liquids could be pumped through the top of the outlet flange.
