Step 2
Locate the rubber stopper. Insert one of the metal
fuel tubes into one of the holes in the stopper so
that an equal amount of tube extends from each
side of the stopper. This tube will be the fuel tank
pickup that provides fuel to the engine.
Step 3
Slide the smaller cap over the tube on the smaller
end of the rubber stopper. This end will be
inserted into the fuel tank. The larger cap is placed
on the side of the rubber stopper that makes
the cap. Loosely install the M3 x 20 screw through
the center of the stopper.

Step 4
Bend the remaining fuel tube carefully to a
45-degree angle using your fingers. This will
be the fuel tank vent tube.
Use care not to kink the tube while bending.
Step 5
Slide the vent tube into one of the remaining two
holes in the stopper from the tank (small cap) side.
