SAE J176_200608 PDF

Description

This SAE Standard applies to off-road self-propelled work machines as categorized in SAE J1116.

A pressurized fast fueling system which requires internal tank pressures to achieve automatic shut-off incorporates a nozzle which is connected to a fueling receiver through which fuel is conveyed to the fuel tank and an automatic shut-off vent to provide automatic fill level control, normal and emergency venting. Nozzles in pressurized systems require an internal automatic shut-off mechanism, which is pressure dependant. Shut-off of fuel into fuel tank is achieved by the nozzle shutting off due to internal fuel tank pressure. Pressurized systems are not recommended on plastic fuel tanks due to the internal tank pressures over 0.5 bar required for shut-off which will damage the fuel tank.

Low pressure systems do not require internal tank pressure to obtain automatic shut-off and require a inlet shut-off valve and signal line in addition to the components in the pressurized system. A nozzle with an automatic shut-off mechanism is not required for fuel shut-off, a dry break may be used for connection to the fuel receiver instead of an automatic shut-off nozzle. Any tank pressures created during a fast fill operation using a low pressure system are less than 0.5 bar.

The purpose of this document is to define the proper installation, position, protection, and size of a fueling receiver, nozzle, automatic shut-off vent connections, signal line, and inlet shut-off valve as required. This document applies to filling diesel fuel tanks or vessels at a flow rate of 570 liters per minute or less. Filling fuel tanks at higher flow rates requires adequately larger diameter components. This specification does not apply to gasoline or other fluids.

Fast fill fueling typically applies to self-propelled machines with a fuel capacity over 380 L or as applicable on machines with less capacity.
