This SAE Recommended Practice covers design and evaluation of the entire gasoline filler pipe assembly used on cars and light trucks with respect to compliance with CARB (California Air Resources Board) LEV II (meeting or exceeding EPA Tier 2 and EU Stage-5 evaporative emissions requirements). It is limited to an assembly which is joined to the fuel tank using either a hose, Quick Connect Coupling, or a grommet type sealing device. The Design Practice covers the filler cap, filler pipe, filler pipe assembly to tank hose, and filler pipe assembly to tank grommet or spud. It includes recommendations for design of components and assemblies intended to perform successfully in evaporative emission SHED (Sealed Housing for Evaporative Determination) tests, based on best practices known at the time of release.

Drop testing and "sled" testing are used regularly to demonstrate integrity of plastic fuel systems. This document defines test method, application and rationale for fuel tank impact testing.

This SAE Standard presents the minimum requirements for nonmetallic tubing with one or more layers manufactured for use as liquid-carrying or vapor-carrying component in fuel systems for gasoline, or alcohol blends with gasoline. Requirements in this document also apply to monowall tubing (one layer construction). When the construction has one or more layers of polymer-based compounds in the wall, the multilayer constructions are primarily for the purpose of improvement in permeation resistance to hydrocarbons found in various fuels. The tube construction can have a straight-wall configuration, a wall that is convoluted or corrugated, or a combination of each. It may have an innermost layer with improved electrical conductivity for use where such a characteristic is desired. The improved electrical conductivity can apply to the entire wall construction, if the tubing is a monowall. (For elastomeric based MLT constructions, refer to SAE J30 and SAE J2405).

This SAE Standard encompasses the recommended minimum requirements for non-metallic tubing and/or combinations of metallic tubing to non-metallic tubing assemblies manufactured as 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 °C (–40 °F) and below 115 °C (239 °F), and up to a maximum working gage pressure of 690 kPa (100 psig). The peak intermittent temperature is 115 °C (239 °F). For long-term continuous usage, the temperature shall not exceed 90 °C (194 °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 accordingly.

This SAE Recommended Practice defines the minimum functional requirements for quick connect couplings used for supply, return, and vapor/emission fuel system connections. This document also defines standard male tube end form dimensions, so as to guarantee interchangeability between all connector designs of the same male tube end form size. This document applies to automotive and light truck applications under the following conditions: a. Gasoline and diesel fuel delivery systems or their vapor venting or evaporative emission control systems; b. Operating pressure up to 500 kPa, 5 bar, (72 psig); c. Operating vacuum down to -50 kPa, -0.5 bar (-7.2 psi); d. Operating temperatures from -40 °C (-40 °F) to 115 °C (239 °F). Quick connect couplings function by joining the connector to a mating tube end form, then pulling back to assure a complete connection. The requirements stated in this document apply to new connectors in assembly operations unless otherwise indicated.
