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.

PARTS REQUIRED
FUEL TANK.
{1} Molded Nylon Fuel Tank
{1} Preassembled Stopper Assembly
{1} Metal Weighted Pick-Up
{1} Silicon tube
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 pickup and the other
end to the nylon pickup tube.
3)
Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.
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.
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.
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
