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, whereit exitsthe fuselagebehindthe
enginemountingbox andtothe rearofthe tank
at the forward bulkhead.
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,the frontof thetank shouldjust about
touch the back of the firewall.
Do not secure the tank into place perma-
nently until after balancing the airplane. You
may need to remove the tank to mount the
battery in the fuel tank compartment
INSTALLING THE STOPPER ASSEMBLY
11.The stopper has beenpre-assembled at
the factory.
12.Usinga modeling knife,cutone length of
siliconfuelline (the lengthof silicon fuel lineis
calculated by how the weighted clunk should
restabout8mm away fromthe rear of thetank
andmove freely inside thetank). Connect one
end of the line to the weighted clunk and the
other end to the nylon pick up tube in the
stopper.
13.Carefully bend the secondnylon tube up
ata 45degree angle(using acigarette lighter).
This tube will be the vent tube to the muffler.
14.Carefullybend the third nylon tubedown
ata 45degree angle(using acigarette lighter).
This tubewill beventtube tothe fuelingvalve.
FUEL TANK.
When the stopper assembly is installed in
the tank, the top of the vent tube should rest
justbelow thetopsurface ofthe tank.Itshould
not touch the top of the tank.
15. Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
amodeling knife. Ifflashing is present, make
sure none of it falls into the tank.
16. When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
machine screw until the rubber stopper
expands and seals the tank opening. Do not
overtightenthe assembly as this couldcause
the tank to split.
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.
