My preference on my Corvair KR2S is to run the header because of my gravity feed carb - Gravity is pretty dependable - I think it is more reliable than a fuel pump (no reported incidents of loss of gravity other than with some assossiated UFO sightings) I have a 13 gallon header and 10 gallons in each wing. Trim is not a big issue and it probably actually helps in that with higher weights I can transfer more fuel to the header to make it more stable in landings. I would opt for a Summit racing tank in the future. You can get a 8 gallon tank that is crash survivable for about 120.00 dollars. Not a bad investment - already has fittings and fuel foam...Just and idea. Bill

I did build the tank with its CG as close to the spar as possible. It will take about 50 litres to fill it. I would like to hear from those who have header tanks (possibly with a corvair). How much does your CG change with fuel burn-off? My fuselage is stock 2S dimensions. Another problem I have if I get rid of the header tank is the sight guage goes with it. I had planned on running from the header tank only with a transfer pump filling the header when necessary. Wing tanks are not full width between the spars either but rather longer, narrower units keeping the fuel close to the CG for minimal influence. Provision will be made to suck direct from the wing tanks should the transfer pump fail. Any information would be greatly appreciated.
