Carefully use a lighter or heat gun to
permenently set the angle of the vent tube.
Important:
When the stopper assembly is in-
stalled 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.
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 pickup 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 3mm 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.
Slide the tank into the fuselage from inside so
that the neck is at the top of the fuselage and
it locates through the engine bulkhead. Gently
secure it to the top horizontal former with a
cable tie.
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
.
Attach the silicone fuel and pressure pipes to
the tank. The lower pipe is the ‘feed’ and the
upper two the ‘pressure and fill’. The fill pipe
is the next pipe.

3) Carefully bend the second nylon tube up
at a 45º angle. This tube is the vent tube.
