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.

This SAE Recommended Practice defines standard tube end form dimensions so as to guarantee interchangeability between all connector designs of the same size and the standard end form. This document also defines the minimum functional requirements for quick connect couplings between flexible tubing or hose and rigid tubing or tubular fittings used in supply, return, and vapor/emissions in fuel systems. 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.

This SAE Recommended Practice defines the minimum functional requirements for quick connectors used in supply, return, and vapor/emissions lines for flexible-tubing systems. This document applies to automotive and light truck gasoline and diesel fuel systems with operating pressure or vacuum up to 500 kPa, 5 bar, (72 psig) and operating temperatures up to 115 °C (239 °F). These tests apply to new connectors in assembly operations. Connectors must be pushed onto a mating tube end then pulled back to assure complete connection. For service operations, the mating tube should be lubricated with SAE 30 weight oil before re-connecting. Vehicle OEM fuel system specifications may impose additional requirements beyond the scope of this general SAE document. In those cases, the OEM specification takes precedence over this document.

This SAE Recommended Practice defines minimum functional requirements for quick connectors used in supply and return, liquid lines, for flexible tubing fuel systems. The document applies to automotive and light truck gasoline and diesel fuel systems, with operating pressures up to 500 kPa, 5 Bar, (72.5 psig), and the fuel lines and connectors routed such that continuous operating temperature exposure is less than 115 °C (239 °F). These tests apply to new fittings in assembly operations: for service operations, the male tube should be lubricated with engine oil before coupling. Vehicle O.E.M. fuel system specifications may impose additional requirements beyond the scope of this general SAE document. In those cases, the O.E.M. specification takes precedence over this document.

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 Surface Vehicle Recommended Practice deals with electrostatic charge phenomena that may occur in automotive fuel systems and applies to the following: Fuels that are in a liquid state at ambient temperatures and atmospheric pressures and are contained in vehicle fuel tanks that operate at or near atmospheric pressure. The group of components that comprise the fuel system (in contact and not in contact with fuels). Other components in proximity to the fuel system that may be affected by electrostatic fields caused by the fuel system. Electrostatic phenomena that arise from or are affected by the following aspects of vehicle or fuel system operation: a Flowing fuel in the fuel delivery system b Flowing fuel being dispensed to the vehicle while it is being fueled

The purpose of this SAE Information Report is to provide a summary of the electrostatic charge phenomenon (as it relates to an automotive fuel system) and how that phenomenon could be handled if it develops. The "fuel system" that is the subject of this document is the group of components used during the operation of the vehicle (tank, filler neck, pump, filter, lines, connectors, etc.). Electrostatic charge that may arise during refueling is also included. It is very important to note that this is a collection of ideas and generalities that are summarized from literature and presentations, inferred from some laboratory experimentation, and interpreted by the Electrostatics Subcommittee of the SAE Fuel Lines and Fittings Standards Committee. Some of the discussions are simplified. If more technical information is needed by users of this document, experts should be consulted or literature should be examined directly.

The purpose of this SAE Recommended Practice is to provide an explanation of electrostatic charge phenomena as they relate to automotive fuel systems and how those phenomena should be handled if they develop. This document is limited to the group of components that are known as the fuel system and only those that handle liquid fuel in one of two situations: operation of the fuel delivery system and refueling of the vehicle. This is a collection of ideas and generalities that are summarized from literature and presentations, inferred from some laboratory experimentation and summarized from experiences within the automotive industry as interpreted by the Electrostatics Subcommittee of the SAE Fuel Lines and Fittings Standards Committee. Some of the discussions are simplified. If users of this document need some further technical information, experts should be consulted or the references cited here should be examined directly.
