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: a Flowing fuel in the fuel delivery system b Flowing fuel being dispensed to the vehicle while it is being fueled

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 test standard covers the procedure for measuring the permeation of fuel or fuel surrogates through test samples of elastomeric, plastic or composite materials, up to about 3 mm thick. The method involves filling a test cup with the test fluid (fuel or fuel surrogate), sealing test sample over the open end of the cup, and then placing the sealed container into an oven at the desired test temperature and measuring the weight loss over time. Permeation rates are calculated from the rate of weight loss and the exposed area of the test sample. Standard permeation test temperatures are 40 °C and 60 °C. Standard test fluids are Fuel C, Fuel CE10 and Fuel CM15. Other fluids, such as Fuel CMTBE15, and other volatile liquids may be tested according to this procedure as desired (SAE J1681). The method is not applicable for measuring permeation of higher boiling materials that will not completely evaporate from the exterior surface of the sample at the test temperature.

This test method described in this document covers a procedure to speciate that is, to determine the amounts of each different fuel constituent that permeates across sheets, films or slabs of plastic materials. One side of the sheet is meant to be in contact with either a liquid test fuel or a saturated test fuel vapor, the other side is meant to be exposed to an environment free of fuel. The test fuel can either be a mixture of a small (usually smaller than ten) number of hydrocarbon, alcohol and ether constituents or it can be a sample of a real automotive fuel, e.g., one that may contain hundreds of different constituents. Furthermore, Appendix A contains guidelines to speciate evaporative emissions from finished fuel system components such as fuel lines, fuel filler pipes, fuel sender units, connectors and valves.

This SAE Recommended Practice defines the minimum functional requirements for quick connect couplings used for supply, return, and vapor/emission fuel system connections. This document also defines standard male tube end form dimensions, so as to guarantee interchangeability between all connector designs of the same male tube end form size. 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.

This SAE Recommended Practice defines the minimum functional requirements for quick connectors used in supply, return, and vapor/emissions lines for flexible-tubing systems. This document applies to automotive and light truck gasoline and diesel fuel systems with operating pressure or vacuum 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 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.
