Quick Connector Specification for Liquid Fuel and Vapor/Emissions Systems
This SAE Recommended Practice defines minimum functional requirements for quick connectors used in supply, return, and vapor/emissions lines for flexible tubing systems. The document applies to automotive and light truck gasoline and diesel fuel systems, with operating pressures 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 reconnecting.
Vehicle O.E.M. 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.
