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.
