Fuel lines and fittings
There are 3 fuel lines that need to be connected in the wing root: the bottom 2 carry fuel to the
header tank while the top line is the breather for the header tank. These fuel lines were cut to
the approximate length in the
Pre-Paint>Fuselage>Interior>Fuel System
task and stored
until now.
All 3 lines exit the wing root towards the rear
and both of the fuel lines will have a spring
fitted to prevent any chance of a kink
developing when the lines are bent to the rear,
while the breather line faces rearwards already.
Fit each fuel line to the tank fitting and secure
with a hose clamp. Slide a 100mm length of
spring over each fuel line, push all the way up
to the hose clamp and fix in place with silicone
sealer at the hose clamp end as shown in the
photo at right.
Label the other end of each fuel line with tape
as shown at right. This is essential because
once the wing has been fitted it will be
very
difficult to determine which line is which if it
has not been labelled.

Fit the fuel gauge windows
Locate the clear, round fuel gauge windows and Superglue them over the outside of the fuel
gauge holes in the wing root area of the fuselage.
