SAE J 2045

This SAE Standard encompasses the minimum requirements for non-metallic tubing and/or combinations of any metallic tubing to non-metallic tubing assemblies manufactured as a liquid- and/or vapor-carrying systems designed for use in gasoline, alcohol blends with gasoline, or diesel fuel systems. This SAE Standard is intended to cover tubing assemblies for any portion of a fuel system which operates above -40 degrees C (-40 degrees F) and below 115 degrees C (239 degrees F), and up to a maximum working gage pressure of 690 kPa (100 psi). The peak intermittent temperature is 115 degrees C (239 degrees F). For long-term continuous usage, the temperature shall not exceed 90 degrees C (194 degrees F). It should be noted that temperature extremes can affect assemblies in various manners and every effort must be made to determine the operating temperature to which a specific fuel line assembly will be exposed, and design according.

The applicable SAE standards should be referenced when design liquid-carrying and/or vapor-carrying systems which are described in this document.
