Install The Cowl Ring, Cowl And Dummy Engine - GREAT PLANES Gee Bee Instruction Manual

2. Install the tank into the fuselage with the neck of the
tank through the firewall. Hold the tank in place inside the
fuselage by wrapping two #64 rubber bands around the
tank, attaching the bands to the tabs in the plywood former
that supports the tank.
3. Install silicone fuel tubing (not included in the kit) onto the
aluminum tubes from the fuel tank. The line with the fuel clunk
will feed to the fuel inlet at the needle valve and the other will
attach to the pressure tap on the muffler. For our installation we
chose to use an external fill valve. If you choose to do this as
well, follow the instructions with your particular brand of fuel
valve. Should you choose not to install a fuel filler valve you
can fill the fuel tank by removing the fuel line to the carburetor
and filling through it. However, depending how you cut out the
cowling to accommodate the engine, the cowling may make it
difficult to access the carburetor.You can also install a third line
to the tank and use it for filling the tank. The method you use
is your choice but make your decision before moving onto the
installation of the fuel tank.

You may already have discovered that the Gee Bee stands
on its tail pretty well. For the installation of the cowl you
will find it helpful to stand the fuselage on its tail.
Temporarily slide the stab into place in the fuselage. This
will aid standing it on the tail. Placing a couple of chairs on
each side of it will prevent it from accidentally falling over!
1. Locate two 1/8" [3mm] plywood cowl rings and four
1/8" [3mm] plywood mounting tabs.
2. Measure up from the bottom of the tab 3/4" [19mm]
and draw a line across it.
3. Stand the fuselage on its tail. Place one of the cowl
rings on the firewall with the tabs of the ring placed as
shown in the picture (this placement is not critical). Make
sure the cowl ring is centered and is an equal distance from
the sides of the fuselage.
4. Using the cowl ring as your reference, mark the locations
for the plywood mounting tabs with a fine tip felt marker.
5. Roughen the area you marked on the firewall with 220-
grit sandpaper. Then wipe the area clean with rubbing alcohol.
