Pre-Paint>Wings>Fit fuel tank filler body
Objectives of this task:
In this task the fuel tank filler body location will be determined for each wing, a hole will be
drilled into the upper wing surface and a smaller hole will be drilled into the wing tank and
then the filler body will be fitted and then flocked into place and covered with peel cloth
while the flock cures.
Materials required:
from Card # J11 „
Fuel Components’
2 x fuel tank filler bodies:
Epoxy resin and flock
Mark the position of the opening
First we need to mark the side-to-side distance from the wing root to the centre of the filler
body opening and in order to do this we must determine the exact length of the wing tank. To
do this take the supplied breather tube and shape the end to a point as shown below. Feed the
breather tube into the tank from the top front wing root fitting and carefully work it past the
tank ribs until you find the end of the tank.
Mark the breather tube level with the wing root at that point then withdraw the tube and mark
where the position of the end of the tank on the top of the wing. Measure back
150mm
from
that point and that is the initial side-to-side location of the filler body. Repeat the process of
finding the end of the tank and measuring back
150mm
on the other wing and then make any
adjustments that may be required to make both filler bodies the same distance from each wing
root. Mark this final side-to-side position of each filler body.
Take a set square and place it under the wing and against the leading edge and then measure
back
395mm
from the leading edge – mark this fore and aft position of each filler body.
