Abstract: A transient suppression device for limiting to desirable levels current and energy entering a fuel tank of an aircraft over interface wiring that penetrates a wall of the fuel tank comprises: an elongated, hollow, conductive housing capped at one end and open at another end, the housing being disposed external and in proximity to the fuel tank, and supported physically from a structure of the aircraft; a transient suppression circuit disposed within the housing and connected in series with the interface wiring; and a shield braid of conductive material disposed over the open end of the housing and covering the interface wiring over the distance between the housing and tank wall, the shield braid electrically coupling the housing to the tank wall. A method of packaging the transient suppression device is also disclosed.

Abstract: An intrusive fluid sensor mounting arrangement for a fluid container includes first and second tubes, the first tube being attachable to a wall of the container such that a first end of the first tube is open to the container exterior through the container wall and a second end of the first tube extends into the container; the second tube being sized to slide axially within the first tube between first and second positions; the second tube having a first end accessible from outside the container such that a sensor can be installed in and removed from the second tube; the second tube providing fluid communication between the sensor and fluid in the container when the second tube is in the first position, and substantially preventing fluid loss from the container when the second tube is in the second position.
