Fuel System Information
Use only fuel as recommended in this section.
Fill the fuel tank at the end of each day of operation to drive out moist air and to prevent condensation. Do not fill the tank to the top. Fuel expands as it gets warm and may overflow.Do not fill the fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to the fuel system parts.
Fuel Tanks
Drain the water and sediment from any fuel storage tank weekly, at the oil change period, and before the fuel tank is refilled. This will help prevent water and/or sediment from being pumped from the fuel storage tank into the engine fuel tank.Fuel tanks should contain some provision for draining water and sediment from the bottom of the tanks.Some fuel tanks use supply pipes that allow water and sediment to settle below the end
