Leak Detection Device

A method comprising:

• additively manufacturing a body having at least one fluid input configured to receive a fluid leak from a first source container, at least one drain configured to be fluidly coupled with one or more of the first source container or a different, second source container, and at least one sensor conduit input configured to be fluidly coupled with at least one sensor,
• the at least one fluid input additively manufactured in the body above the at least one drain but below the at least one sensor conduit input in the body,
• the body additively manufactured to include an internal conduit that is fluidly coupled with and extends between the at least one fluid input, the at least one drain, and the at least one sensor conduit input, the internal conduit additively manufactured to include a lower branch that extends in the body below the at least one fluid input to the at least one drain, the internal conduit additively manufactured to include an upper branch that separately extends in the body above the at least one sensor conduit input to the at least one drain,
• the lower branch of the internal conduit additively manufactured to include a reduced flow portion having a smaller cross-sectional size than the upper branch of the internal conduit, the internal conduit additively manufactured to have the reduced flow portion below the at least one fluid input and the at least one sensor conduit input but above the at least one drain.

A vehicle fuel leak detection device comprising:

• a body having at least one fluid input configured to receive a fuel leak onboard a vehicle, at least one drain configured to be fluidly coupled with a fuel tank of the fuel, and a first sensor conduit input configured to be fluidly coupled with a fluid sensor,
• the at least one fluid input disposed in the body above the at least one drain but below the at least one sensor conduit input in the body,
• the body including an internal conduit raceway that is fluidly coupled with and extends between the at least one fluid input, the at least one drain, and the at least one sensor conduit input, the internal conduit including a lower branch that extends in the body below the at least one fluid input to the at least one drain, the internal conduit including an upper branch that separately extends in the body above the at least one sensor conduit input to the at least one drain,
• the lower branch of the internal conduit including a reduced flow portion having a smaller cross-sectional size than the upper branch of the internal conduit, the internal conduit having the reduced flow portion below the at least one fluid input and the at least one sensor conduit input but above the at least one drain.
