1. Drill a 3/16" [4.8mm] hole near the edge of the fuse

and aligned with the throttle arm.

❏

2. Roughen the outside of the 11-3/4" [300mm] gray

pushrod outer tube with coarse sand paper. Fit the tube
through the firewall leaving 1/8" [3mm] protruding from the
firewall. Glue the tube to the firewall with thin CA.

❏

3. Arrange the stopper and tubes as shown in the photo,

then insert them into the tank. Tighten the screw to expand
the stopper, thus sealing the tank. Be certain the fuel line
weight (clunk) at the end of the fuel line inside the tank does

not contact the rear of the tank. Otherwise, the line may
become stuck above the fuel level and discontinue fuel flow.
Remember (or use a felt-tip pen to mark) which tube is the
fuel pick-up tube and which tube is the vent (that will be
connected to the pressure fitting on the engine’s muffler).

❏

4. Install the tank in the fuse. Fit the neck through the

hole in the firewall. Be certain the vent tube inside the tank
is pointing upward.

❏

5. Glue a 3/16" x 3/4" x 2-7/8" [5 x 19 x 72mm] balsa

block to the fuse to hold the tank in place.
