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 These definitions are no longer valid.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.

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.

This recommended practice defines conditions for evaluating the compatibility of vehicle fuel tanks and filler pipes with fuel dispensing facilities equipped with standard (non-vapor recovery) configuration as well as vapor recovery type nozzles. It applies to passenger cars, multi-purpose passenger vehicles, and light-duty trucks (10 000 lb (4536 kg) maximum gvw), (Ref. J1100, Motor Vehicle Dimensions). It includes a technique for filling a tank full that can be used to establish a reference condition for other tests which require starting with a full tank.

This SAE Recommended Practice covers design and evaluation of the entire gasoline filler pipe assembly used on cars and light trucks with respect to compliance with CARB (California Air Resources Board) LEV II (meeting or exceeding EPA Tier 2 and EU Stage-5 evaporative emissions requirements). It is limited to an assembly which is joined to the fuel tank using either a hose, Quick Connect Coupling, or a grommet type sealing device. The Design Practice covers the filler cap, filler pipe, filler pipe assembly to tank hose, and filler pipe assembly to tank grommet or spud. It includes recommendations for design of components and assemblies intended to perform successfully in evaporative emission SHED (Sealed Housing for Evaporative Determination) tests, based on best practices known at the time of release.

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. This includes gasoline and diesel fuels, as well as their blends with additives such as alcohols, esters, and ethers, whether the additives are petroleum based or bio-fuel based. 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: ○ Flowing fuel in the fuel delivery system. ○ Flowing fuel being dispensed to the vehicle while it is being fueled.

This SAE Recommended Practice provides standardized dimensions for nozzle spouts and a system for differentiating between "unleaded gasoline" nozzle spouts and all other fuel nozzle spouts. If emission control equipment requires unleaded gasoline exclusively and other fuels not meeting this specification are available, differentiation is accomplished by providing differences between the outside diameter of the nozzle spouts used to dispense "unleaded gasoline" and those used for all other fuels. These differences establish a basis on which fuel filler inlets that will accept only "unleaded gasoline" can be designed. Spouts used to dispense "unleaded gasoline" should have a nominal OD of 20.6 mm (13/16 in) and be straight for 85 to 95 mm (3.35 to 3.74 in) from the outlet. It is understood that tolerances and normal use may increase the spout up to 21.3 mm (0.84 in) OD. The spouts for all other fuels should have a nominal OD of 23.8 mm (15/16 in) or more.

This SAE Recommended Practice presents recommendations for test fuels and fluids that can be used to simulate real world fuels. The use of standardized test fluids is required in order to limit the variability found in commercial fuels and fluids. Commercial fuels can vary substantially between manufacturers, batches, seasons, and geographic location. Further, standardized test fluids are universally available and will promote consistent test results for materials testing. Therefore, this document: a Explains commercial automotive fuel components b Defines standardized components of materials test fluids c Defines a nomenclature for test fluids d Describes handling and usage of test fuels e Recommends fluids for testing fuel system materials The test fluid compositions specified in Section 7 of this document are recommended solely for evaluating materials.

This SAE Recommended Practice applies to determining worst-case fuel or test fluid surrogate, conditioning test specimens in worst-case fuel(s)/surrogate(s) prior to testing, individual tests for properties of polymeric materials exposed to oxygenate fuel/surrogate mixtures with additives. The determination of equilibrium, as well as typical calculations are also covered.

This SAE Standard covers the minimum requirements for nonmetallic tubing as manufactured for use in gasoline or diesel fuel systems. It is not intended to cover tubing for any portion of the system which operates below -40 °C, above 115 °C, or above a maximum working gage pressure of 690 kPa.

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).
