On my Garmin 96 there is a built in fuel timer - set it for however
many minutes you want between changes and it somehow knows when you're
flying and when you're not, and lets you know when a tank change is
due.

My 196 has a similar feature, although I usually use a separate timer,
or just put a mark on my flight plan when I should switch. What a
REALLY want is just a simple countdown-type timer that signals when
time is up by flashing a large bright light that I can't miss, similar
to the big red stall warning light on the instrument panel of my
Cherokee. I've never found one for sale, but I've thought about
trying to construct one with my rudimentary electronics skills and a
bunch of Radio Shark parts.
