Abstract
A fuel delivery system for an internal combustion engine system is described herein. The fuel delivery system uses one or more bidirectional purge components to provide for bidirectional purging of a fuel from at least a portion of the fuel delivery system. The bidirectional purge components provide for a fuel delivered using the fuel delivery system to be purged into the directional purge component in more than one fluid flow direction. When a differential pressure is applied across the bidirectional purge component, the fuel is purged into an inlet and an outlet of the bidirectional purge component, leaving the component through a purge outlet and into a tank. The differential pressure can be generated using a pressured fluid such as nitrogen or a pump downstream of the purge outlet.
