Day Tank Condensation Drain

FPB-64-fuel-system-106

The valve center bottom in the photo above is a small but important detail. This is the condensation drain on the engine room day tank. Note the pipe plug in the valve as a double check. The valve is threaded into a small sump making it easier for water and other gunk to collect at the low point. Normally a sump like this would be drained once a season and you might find a quart/liter of water at the most.

    Steve,

    This is a great and accessable detail for the fuel system and, as a pilot, reminds me of what is just standard daily practice on airplanes where fuel integrity is so important.

    your thoughtfulness in systems design sets a standard in the industry

    thank you for sharing on a regular basis

    best,
    Scott

    Hi Scott:
    Thanks for the kind words. Rather than checking on each flight as you do with an airplane we usually drain once a season.
