fuel sending units/Shadin totalizers

[jchronic]

I think Mark's point is spot on - and important. I have a Shadin, have found it to be extremely accurate, and depend on it, along with a time flown/estimated fuel used plot. BUT, as he rightly points out, if you're leaking fuel somewhere the Shadin isn't going to show it. I rely on the Shadin, but also maintain at least my main fuel gauges as a cross check.
