Result: A fuel shut-off valve is not fully open.
Repair: Move all shut-off valves to the fully open position.
Result: All shut-off valves are in the fully open position.
Proceed to Test Step 3.
3. Fuel Level in Tank
Note: If the level in the fuel tank is low, the hot return fuel can raise the temperature in the fuel tank.
A. Check the fuel level in the tank.
Fuel level
Result: The fuel level in the tank is low.
Repair: Replenish the fuel tank at the earliest opportunity.
Result: The fuel level in the tank is OK.
Proceed to Test Step 4.
4. Return Fuel Cooler
