Hey Larry: As you noticed, the header tank fuel quantity gauge goes down
rather quickly. I believe if it is working properly, it will show empty when
you have about 30 minutes of engine running/flying time left. All the ones
I have calibrated start to show fuel at just under 3 gallons. So it sounds
like yours is operating properly. It can easily be calibrated by draining
the fuel, adding one gallon at a time, and marking where the float indicator
indicates. I think you will find the same thing I have mentioned above.
The engine type/model makes no difference. (Only in the time remaining
when the bobber is showing empty)

I have just purchased a 415-D with the O-200 conversion. In draining the
header tank I noticed that the sight gauge indicator dropped out of sight
long before the tank ran dry. Also, one trip around the pattern with the
electric pump off resulted in an indicator half way down the glass tube. I
realize that in a Coupe with an engine driven fuel pump the pump keeps the
tank
fuel. With the O-200, the electric pump is turned on to fill the tank and
turned off when it's full. My question is what does the header tank level
indicator represent? Does it's level indicate the amount of fuel in the
tank-as would seem reasonable. Maybe someone with the conversion could give me
some guidance. Thanks.
