I ALWAYS fly by time (3 hours on the tach from >full tanks to refueling) I've noticed that I get about the same RPM in level flight firewalled, or with the throttle pulled back out a ways, but the difference is speed. I know I'm using more gas with the throttle open, so I guess for me using tach time wouldn't be great. Of course my comfort duration is exceeded by fuel capacity, so that's quite a safety factor. :-) >but the header gauge is not a fuel gauge - it is a fuel pump fail >indicator <g> It's a pretty good warning that you've got under an hour left to fly, however that may have come about. >. Seriously, If the header gauge starts to drop I get very nervous. So do I, and due to the funny shape of the tank, it does tend to be lower when leveling out from a climb (at least on my fuel system). I always watch it with keen interest until it comes back up to the red pony-tail holder around the glass tube that I use as a nominal level indicator. Actually, one of the reasons I like the rain-pruf gauge is that it is possible to have markings. The illusion that the wire is sinking is something akin to 'automatic rough' that engines develop over water. > I try to always refuel before it happens.

Like I said, I lose interest in the whole subject of continuing to fly between 30 and 60 minutes before going through the contents of the wing tanks. Gross weight limitations aside, that generally is a pretty good safety factor! But I've never liked flying in circumstance where there was any question about having enough gas to get to the next fuel stop. I'm starting to learn that 8 gallons (in the 9 gallon tanks) is a more realistic capacity to pump to. Given that fuel moves around the system, if you fill up to 9 per side when the header is full, as it almost always is after landing, there ends up being no room for 'tilt' factor, and a modicum of gas ends up spewing from one of the wing tank vents.
