Abstract
A novel drain system for venting excess fuel from the fuel pump of a jet engine, and particularly the augmenter pump of a jet engine afterburner, is described which comprises a drain line connected at a first end to the vent valve of the fuel pump and at a second end to the main fuel supply line for the engine, for draining the excess fuel from the pump to the main fuel line, a check valve in the drain line near the second end thereof for restricting fuel flow through the drain line in a direction from the first end to the second end, and a vent line having a restriction therein defining an orifice of predetermined size connecting the drain line to an overboard dump port open to ambient.
