Adding a Fuel Stabilizer to Extend Fuel Storage Life
Short Term Storage (30-90 days)
If your equipment will not be used for 30-90 days, we recommend the
following to prevent fuel-related problems.
1. Add fuel stabilizer following the manufacturer's instructions.
When adding a fuel stabilizer, fill the fuel tank with fresh gasoline. If
only partially filled, air in the tank will promote fuel deterioration
during storage. If you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline.
2. After adding a fuel stabilizer, run the engine outdoors for 10 minutes
to be sure that treated gasoline has replaced the untreated gasoline
in the carburetor.
Dry operation will damage the pump seal. Be sure the pump
chamber is filled with water before starting the engine.
3. Stop the engine.
4. Remove the pump drain plug, and allow the water to drain from the
pump chamber. Reinstall the drain plug.
