2.3.4.2
Special Precautions for Diesel Fuels. While not as
critical as with aviation turbine fuels, diesel fuel systems
are subject to damage by dirt and water in the fuel. Avoid
In cold climates, provide designs that will prevent "gelling."
Provide a design that precludes disposing of diesel fuels into
storm or sanitary sewers.

Special Precautions for Burner Fuel Oils. When the
ambient temperature of the burner fuel oil is less than
20 degrees F (11 degrees C) above the pour point temperature,
the burner fuel oil needs to be heated. At the burner fuel
