INSTALLING THE STOPPER ASSEMBLY.

1) Using a modeling knife, carefully cut
off the rear portion of one of the 3 nylon tubes
leaving 1/2" protruding from the rear of the
stopper. This will be the fuel pick up tube.
2) Using a modeling knife, cut one length
of silicon fuel line. Connect one end of the line
to the weighted fuel pick up and the other end
to the nylon pick up tube.

3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.
4) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using a
modeling knife. If flashing is present, make
sure none falls into the tank.
5) With the stopper assembly in place,
the weighted pick-up should rest away from
the rear of the tank and move freely inside the
tank. The top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
6) When satisfied with the alignment of
the stopper assembly tighten the 3 x 20mm
machine screw until the rubber stopper ex-
pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.

FUEL TANK INSTALLATION.

You should mark which tube is the vent
and which is the fuel pickup when you attach
fuel tubing to the tubes in the stopper. Once
the tank is installed inside the fuselage, it may
be difficult to determine which is which.
7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in the
firewall.
