Book Description
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).Unless otherwise agreed to by suppliers and users this document applies to tubing for any portion of the fuel system that might operate continuously at temperatures above 40 °C and below 90 °C and up to a maximum working gage pressure of 450kPa. The tubing can be used at the peak intermittent temperature up to 115 °C.This document can apply to systems that operate at higher pressures and/or are exposed to higher temperatures. For higher pressures, the acceptance criteria of section 7.2 must be correspondingly changed. For higher temperatures, the acceptance criteria of sections 7.2 and 7.14 remain the same, but apply at the higher temperature. The selection of higher temperatures and pressures that could be used for this document would be the decision of the end user and supplier of the specific fuel/fuel vapor system in question.There are three types of tubing covered by this specification, based on the type of application for which the tubing is intended to be used: High pressure, liquid fuel line is tubing that handles liquid fuel at pressures up to 450 kPa pressure, and can handle the maximum pressure requirements identified in sections 7.1 and 7.2. These are typically the smaller diameter tubes identified in Table A1. Low pressure, liquid fuel line is tubing that is regularly exposed to liquid fuel, but is subjected to pressures that are under 50 kPa (e.g. fuel filler pipes). These are typically the larger diameters identified in Table A1. Fuel vapor tubing is tubing that handles fuel in vapor form or some liquid condensed from vapor, and operates at a working gauge pressure that does not exceed 20 kPa.In some cases, a distinction is made in the criteria that apply to tubing used to carry liquid fuel compared to tubing used to carry fuel vapor. These are identified separately in each section.

Book Description
This SAE Standard covers the minimum requirements for multilayer, nonmetallic tubing as manufactured as a liquid-carrying or vapor-carrying component for use in gasoline, alcohol blends with gasoline, or diesel fuel systems. Monowall tubing (one layer construction) is also covered by this document. The construction has one or more layers of polymer-based compounds in the wall, primarily for the purpose of improvement in permeation resistance to hydrocarbons found in various fuels. The construction can have a straight-wall configuration or can have a wall that is partially convoluted or corrugated. It may have an innermost layer with improved electrical conductivity for use where such a characteristic is desired; also, the improved electrical conductivity can apply to the entire wall construction, if the tubing is a monowall. This document is intended to cover tubing for any portion of a fuel system which operates above -40°C, and below 115°C, and up to a maximum working gage pressure of 690 kPa. The peak intermittent temperature is 115°C. For long-term continuous usage, the temperature shall not exceed 90°C. In some cases, a distinction is made in the criteria that apply to tubing used to carry liquid fuel compared to tubing used to carry fuel vapor. The term "fuel vapor" can also apply to evaporative emissions and refers to a condition where the fuel content is in vapor form (very low concentration) and operated at a working gage pressure that does not exceed 17 kPa. The fuel vapor, or evaporative emissions, may contain small quantities of liquid fuel, which are present primarily as a result of vapor condensation.
