Fuel Tank
Fuel quality is critical to the performance and to the
service life of the engine. Water in the fuel can cause
excessive wear to the fuel system. Condensation
occurs during the heating and cooling of fuel. The
condensation occurs as the fuel passes through the
fuel system and the fuel returns to the fuel tank. This
causes water to accumulate in fuel tanks. Draining
the fuel tank regularly and obtaining fuel from reliable
sources can help to eliminate water in the fuel.
Drain the Water and the Sediment
Fuel tanks should contain some provision for draining
water and draining sediment from the bottom of the
fuel tanks .
Open the drain valve on the bottom of the fuel tank
in order to drain the water and the sediment. Close
the drain valve.
Check the fuel daily. Drain the water and sediment
from the fuel tank after operating the engine or drain
the water and sediment from the fuel tank after the
fuel tank has been filled. Allow five to ten minutes
before performing this procedure.
Fill the fuel tank after operating the engine in
order to drive out moist air. This will help prevent
condensation. Do not fill the tank to the top . The
fuel expands as the fuel gets warm . The tank may
overfiow.
Some fuel tanks use supply pipes that allow water
and sediment to settle below the end of the fuel
supply pipe. Some fuel tanks use supply lines that
take fuel directly from the bottom of the tank. If
the engine is equipped with this system, regular
maintenance of the fuel system filter is important.
Fuel Storage Tanks
Drain the water and the sediment from the fuel
storage tank during the following conditions:
• Weekly
• Oil change
Refill of the tank
This will help prevent water or sediment from being
pumped from the storage tank into the engine fuel
tank.
