We suggest using a quality 16 oz (500cc) fuel tank suited
for gasoline such as Fourtitude, Dubro, or Sullivan. Begin
assembly by bending the longest copper tube as a vent
line. (Bend it a little at a time to prevent collapsing the
tube.) Slide on the smaller stopper pressure plate with
the tapped hole in it. Slide on the rubber stopper. Then
slide on the larger pressure plate. Insert the 2 remaining
copper tubes for a fill line and the carburetor supply line.
Loosely add the machine screw to hold the assembly
together. Slide the clunk (fuel pickup) onto the fuel line
then slide the fuel line onto one of the copper tubes.
Insert the assembly into the fuel tank and check that the
clunk if free to move around. Rotate the tank side to side
and upside down to ensure the clunk does not get stuck.
If cluck does not move freely in all positions trim a little
off the fuel line and try it again. When you have
established the correct length of the fuel line you can
tighten the stopper screw.
The fuel tank vent line should loop up over the tank then
exit through the bottom of the airplane. The fill line
should be capped by a fuel dot. The carburetor supply
line should run to a fuel line filter then through the
firewall to the carburetor.
Position the fuel tank in front of the wing tube. Placing a
piece of foam under the tank will prevent fuel foaming
from vibration. Secure the tank using the hook and loop
straps running through the slots on the plywood tray. We
recommend using at least a 1” stra
p if you intend to do
high G, 3D maneuvers.
