Nonmetallic Fuel System Tubing with One or More Layers
- Ground Vehicle Standard
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.

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.
