SAE J 1140:2019-10-02

This SAE Recommended Practice was developed primarily for gasoline-powered passenger car and truck applications to interface vapor recovery systems, but may be used in diesel applications, marine, industrial, and similar applications where a nozzle is required for filling. The zones cover nozzle spout access and handle clearance to a refilling port. In addition, this practice includes a design window for nozzle manufacturers to develop with.
