This patent describes a lightning-protected fuel drain valve. It comprises means forming a non-conductive plastic housing connectable to a fuel tank and having a port opening exteriorly of the housing and the fuel tank, a non-conductive plastic valve member guided for movement along an axis extending through the housing and the port between a first position wherein a lower end portion thereof closes the port and a second position wherein the lower end portion is raised to open the port. It has bias means operatively engaged with the valve member to bias the valve member in a direction along the axis that would extend the valve member downwardly of the port and the housing, cooperating stop means connected with the valve member for movement therewith and first abutment means fixed relative to the housing for preventing to the valve member from passing downwardly out of the port, second abutment means fixed to the housing in confronting relation to the first abutment means and cooperating with the stop means for preventing the valve member from moving upwardly along the axis by a distance sufficient that the outer end portion moves away from the port to open the same unless the valve member is first rotated about the axis to maintain the valve member in a port-closed position in the event of a lightning strike.
