Fuel Tank Installation - Seagull Models PC-9 Assembly Manual

5) 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.
6) 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.
7) 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.

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.
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.
