STORAGE
PUMP STORAGE
For storage of the pump for over 30 days, the following is
required:
Drain the fuel tank completely.
Run the engine until the fuel is completely consumed.
Completely drain used oil from the engine crankcase
and fill with fresh clean oil, then follow the procedures
described in the engine manual for engine storage.
Remove the drain plug from the pump and drain out any
water from left in the housing.
Remove the pump cover and clean inside of pump
housing. Coat inside of pump housing with a light film
of oil to reduce corrosion. A spray can of oil works well
for this application.
Cover suction and discharge ports with duct tape to
prevent any foreign matter from falling into pump.
Cover pump and engine with plastic covering or
equivalent and store in a clean, dry place.
To protect the water cooled-seals, place one-half pint
of lubricating oil (new or used) through the discharge
opening on the pump and crank the engine several times.
This will prevent excessive corrosion and also keep the
mechanical seal lubricated.
