❑
Carefully bend the longer of the two aluminum tubes up at a 45º angle, being careful not to "kink" the tubing as you
bend it.

When the stopper assembly is installed in the fuel tank, the top of the vent tube (the tube you just bent)
should rest just inside the bubble in the top of the tank.
❑
Push the M3 x 20mm machine screw through the stopper assembly, from the front, and partially thread it into the small
diameter metal backplate.
❑
Secure one end of the silicon fuel tubing onto the end of the
fuel pick-up "clunk."
❑
Slide the silicon fuel tubing, with the fuel pick-up attached,
onto the end of the aluminum fuel pick-up tube (straight tube).
While holding the aluminum tube in place, adjust the length of
the silicon tubing until the fuel pick-up is 4-3/8" back from the
rear of the stopper assembly.
STEP 2: INSTALLING THE RUBBER STOPPER ASSEMBLY
❑
When satisfied with the alignment, tighten the machine screw until the rubber stopper expands and seals the fuel
tank opening.

Don't overtighten the machine screw or you might strip the threads in the small metal plate.
❑
With the rubber stopper assembly installed, double-check to make sure that the fuel pick-up can move freely inside the
fuel tank. Ideally, the fuel pick-up should be about 1/4" in front of the back of the fuel tank.
❑
Carefully push the metal neck-reinforcement ring over the
neck of the molded fuel tank opening.
❑
Carefully push the rubber stopper assembly into the fuel
tank opening and rotate the stopper assembly until the aluminum
vent tube rests just inside the bubble in the top of the tank.
If you have trouble seeing the vent tube, hold
the fuel tank assembly up to a bright light. This will illuminate
the inside of the tank.

STEP 3: INSTALLING THE FUEL TANK
❑
Cut two pieces of silicon fuel tubing to a length of 12".
❑
Feed the ends of the fuel tubing into the predrilled holes in the firewall and through the predrilled holes in the
forward bulkhead.
To make this task easy, use a small diameter stick, or even better, the threaded rudder pushrod wire, to use
as a guide to feed the fuel tubing through the holes.
