HEADER TANK INSTALLATION
..... It is much easier to install the header tank prior to mounting
the canard to the fuselage.
..... Install the header tank using 2 BID and flox where it meets the
inside fuselage skin.
..... As a reminder, prior to permanently mounting the fuel header
tank, make sure that it will not interfere with instruments, feet,
rudder pedals, engine installation, etc. In order to maximize the
fuel quantity_ it has been made a tight fit in the forward fuselage.
HEADER TANK FUEL GAUGE
..... It is necessary for the fuel header tank to have a fuel gauge
to detect any failure of the fuel transfer system that would result
in a reduced level of the header tank.
..... A very simple arrangement of clear plastic tubing is used to
create a sight fuel gauge. It is floxed in place at the top and
bottom of the fuel header tank, and then run aft through the
instrument panel into the cockpit where it is turned vertically as
shown.
..... Later, calibrate the gauge with the fuselage leveled with
respect to WL15 by adding fuel in one gallon increments and marking
the clear plastic tube. A similar calibration is performed on the
main fuel tank gauge.
..... It is important to note that the gauge will only be accurate
while in straight and level flight. Particularly in the case of the
fuel header tank gauge small changes in aircraft attitude will make
large changes in the indication of fuel quantity. The fuel header
tank gauge should be used only to verify that the fuel header tank is
maintaining a full level in straight and level flight.
..... Also note that the fuel header tank gauge cannot be installed
