This SAE Recommended Practice was developed to standardize fuel inlet closure colors and verbiage by fuel type primarily for passenger car and truck applications, but it can be applied to marine, industrial, lawn and garden, and other similar applications. See Section 4, Table 1 for a list of specified colors, and text by fuel type.

This SAE Standard encompasses the minimum functional requirements for fuel tubing and nonmetallic and nonrubber hose assemblies to be used in gasoline fuel injection systems. It utilizes information from the tubing standard SAE J2043, fittings and connectors SAE J2044, and protective covers SAE J2027. It is not intended to cover assemblies that operate below 30 °C (-22 °F) or above 115 °C (239 °F). In addition, this document is applicable for gasoline F.I. systems up to 5 bar (approximately 75 psig) operating pressure. It should be noted that temperatures can affect assemblies in various manners and every effort must be made to determine the operating temperature to which a specific assembly will be exposed, and design accordingly. This document does not make recommendations as to which assemblies are appropriate for different ranges of operating temperatures.

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 is intended for the determination of the losses of hydrocarbon fluids, by permeation through component walls as well as through "microleaks" at interfaces of assembled components while controlling temperature and pressure independently of each other. This is achieved in a recirculating system in which elements of a test fuel that permeate through the walls of a test specimen and migrate through the interfaces are transported by a controlled flow of dry nitrogen to a point where they are measured. That measurement point is a device, such as a canister containing activated charcoal or other means of collection or accumulation where the hydrocarbon losses are then measured by weight change or analyzed by some other suitable means.

This test method is intended for measuring fuel permeation at elevated temperature through low permeating hose or tubing samples of elastomeric or composite construction. The expected accuracy of the method is about ±10% of the sample permeation rate. Hose permeation testing can be done two ways: Method A – Plug and Fill or Method B – using a fuel reservoir. Method A involves plugging one end of the hose, filling the sample to about 90% full with test fuel, plugging the other end, and then exposing the plugged sample to a desired test temperature, with the weight loss measured over time. Method B involves plugging one end of a hose, and then connecting the other end to a fuel reservoir. The hose sample and reservoir are then exposed to a desired test temperature with the weight loss measured over time. This procedure presents a recommended plug design that permits inserting the plugs prior to adding the test fluid.

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.
