I just went back and re-read the story and realized that this was not truly a garmin problem. The modified fuel system caused the problem and those additions are outside the design envelop of the garmin system.

I most strenuously disagree. Systems should be designed NOT to fail
catastrophically when outside their "intended use". The problem was
=not= caused by the modified fuel system, rather, the problem was caused
by unexpected sensor input. In this case the unexpected sensor input
was caused by the modified fuel system, but it could have come from any
number of reasons, and the whole point of aviation systems is that they
be robust.
