you were about to run out of gas when you had plenty.
There are a number possible explanations, but the first one
that comes to mind is that your fuel pump is getting feeble.
If electrical (i.e. O-200 conversion) also check to see that your
battery voltage was where it should be. And check for the
usual pump problems (easy to do a flow-test on these
babies).
If mechanical, check for the usual pump-ish problems. Plus
check that a shy mechanic (shy of stripping threads) didn't
under-torque the bolt in the top of it and thus allow the pump
to 'suck air' around the edge of the dome.

Dear Coupers,
I've a mystery that needs solving.
Last week I flew from my home field in Jacksonville Fl. to Hilton Head SC. My intention was to fly direct to Varnville SC but the sight tube on the header tank was below the half way mark and I stopped at Hilton Head to check it out. I put 11.7 gal. of fuel in the bird which gave me about 6 gal per hour burn.
My question is this. If the fuel is pumped from the main wing tanks into the header tank and then gravity fed to the carb. Shouldn't the header tank remain full until the wing tanks are empty? If so. Why would the fuel pump not keep up with fuel burn...assuming the excess goes back into the wing tanks? Or...is there another problem?
Any suggestions?
Thanks,
John B.
