Quick Connector Specification for Liquid Fuel and Vapor/Emissions Systems
- Ground Vehicle Standard
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. The requirements stated in this document apply to new connectors in assembly operations unless otherwise indicated. 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.

The Fuel Systems Standards Committee reports to the Powertrain Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to all aspects of the vehicle fuel system from the connections to the engine back to the gas cap including the interface between the vehicle fuel system and refueling infrastructure at fueling stations. The Committee¿s scope only includes liquid fuels such as gasoline, diesel and alternative fuel blends, and, as a contributor to ISO work, the committee covers gaseous fuels such as natural gas, LPG and hydrogen. Participants in the SAE Fuel Systems Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.
