Fuel Storage; Servicing The Fuel Tank; Inspecting The Fuel Lines And Connections - Toro Reelmaster 3100-D Operator's Manual

If you do not follow the procedures for fuel filter replacement, fuel system
maintenance, and fuel storage, the engine fuel system could fail prematurely. Perform
all fuel system maintenance at the specified intervals or whenever the fuel is
contaminated or its quality is poor.

Fuel Storage

Appropriate fuel storage is critical for your engine. Proper maintenance of fuel storage tanks
is often overlooked and leads to the contamination of fuel delivered to the machine.
• Acquire only enough fuel that you will consume within 180 days. Do not use fuel that has
been stored for more than 180 days. This helps eliminate water and other contaminates
in the fuel.
• If you do not remove the water from the storage tank or machine fuel tank, it can lead to
rust or contamination in the storage tank and fuel system components. Tank sludge
developed by mold, bacteria, or fungus restricts flow and clogs the filter and fuel
injectors.
• Inspect your fuel storage tank and machine fuel tank regularly to monitor the fuel quality
in the tank.
• Ensure that your fuel comes from a quality supplier.
• If you find water or contaminants in your storage tank or machine fuel tank, work with
your fuel provider to correct the problem and perform all fuel system maintenance.
• Do not store diesel fuel in tanks or canisters made with zinc-plated components.

Servicing the Fuel Tank

1. Prepare the machine for maintenance.
2. Drain and clean the tank if the fuel system becomes contaminated or if the machine will
be stored for an extended period. Use clean fuel to flush out the tank.

1. Prepare the machine for maintenance.
2. Unlatch and open the hood.
3. Inspect the fuel lines and fittings for deterioration, damage, or loose connections.
Note:
