Refill the fuel tank at the end of each day's operation to prevent condensation from contaminating the fuel.
A galvanized steel tank should never be used for fuel storage because the fuel oil reacts
chemically with the zinc coating to form powdery flakes which quickly clog the fuel strainer and
filter and damage the fuel pump and the fuel injectors.
Engine Out of Fuel
The problem in restarting the engine after it has run out of fuel stems from the fact that after the fuel is exhausted from the
fuel tank, fuel is them pumped from the primary fuel strainer and sometimes partially removed from the secondary fuel
filter before the fuel supply becomes insufficient to sustain engine firing. Consequently, these components must be refilled
with fuel and the fuel pipes rid of air in order for the system to provide adequate fuel for the injectors.
When an engine has run out of fuel, there is a definite procedure to follow for restarting the engine.
1. Fill the fuel tank with the recommended grade of fuel oil. If only partial filling of the tank is possible, add a
minimum of ten gallons (38 litres) of fuel.
2. Remove the fuel strainer shell and element from the strainer cover and fill the shell with fuel oil. Install the shell
3. Remove and fill the fuel filter shell and element with fuel oil as in Step 2.
4. Start the engine. Check the filter and strainer for leaks.
In some instances, it may be necessary to remove a valve rocker cover and loosen a fuel pipe nut
in order to bleed trapped air from the fuel system. Be sure the fuel pipe is retightened securely
before replacing the rocker cover.
Primer J 5956 may be used to prime the entire fuel system. Remove the filler plug in the fuel filter cover and install the
primer. Prime the system. Remove the primer and install the filler plug.
