This SAE Recommended Practice provides standard dimensions for liquid fuel dispenser nozzle spouts and a system for differentiating between nozzles that dispense liquid fuel into vehicles with spark ignition (SI) engines and compression ignition (CI) engines for land vehicles. Current legal definitions only distinguish between “Unleaded Fuel” and “All Other Types of Fuel.” These definitions are no longer valid. This document establishes a new set of definitions that have practical application to current automobile liquid fuel inlets and liquid fuel dispenser nozzle spouts.
Rationale
With the introduction of Phase II Enhanced Vapor Recovery nozzles and automotive fuel system designs that utilize capless filler receptacles, improved definition of the interface for the fuel dispenser nozzle spout is required. This document is intended to give a general dimensional layout for conventional petrol, Enhanced Conventional (ECO) petrol, Phase II petrol, and Phase II Enhanced Vapor Recovery (EVR) petrol dispenser spouts, which are used to refuel a wide range of vehicles. Specifying general dimensional requirements will ensure compatibility between the nozzle and vehicle fill pipe interface.
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.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
