tank. It may be necessary to remove some of
the flashing around the tank opening using
amodelingknife. Ifflashing is present, make
sure none of it falls into the tank.
17. Using a modeling knife, cut 3 lengths of
fuel line 150mm long. Connect 2 lines to the 2
vent tubes and 1 line to the fuel pickup tube in
the stopper.
When the stopper assembly is installed
in the tank, the top of the vent tube should
rest just below the top surface of the tank.
It should not touch the top of the tank.
18. Feed three lines through the fuel tank
compartment and through the pre-drilled hole
in the firewall. Pull the lines out from behind
the engine, while guiding the fuel tank into
place. Push the fuel tank as far forward as
possible,thefrontofthetankshouldjustabout
touch the back of the firewall.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow
through easily.
19. To secure the fuel tank in place, apply a
bead of silicon sealer to the forward area of
thetank,whereitexitsthefuselagebehind the
