Claim 3:
4. The fuel delivery system of claim 3, further comprising a purge cutoff valve configured to fluidically disconnect the pressurized fluid from the inlet of the bidirectional purge component, wherein when the purge fluid valve is open and wherein:
when the purge cutoff valve is open and the bypass valve is shut, the pressurized fluid forces the fuel into the inlet of the bidirectional purge component;
when the purge cutoff valve is closed and the bypass valve is open, the pressurized fluid forces the fuel into the outlet of the bidirectional purge component; and
when the purge cutoff valve is open and the bypass valve is open, the pressurized fluid forces the fuel into the inlet and the outlet of the bidirectional purge component simultaneously.
