Section 9: Assembling & Installing the Fuel Tank
Step 4. Slide this tube into the remaining hole in the black
rubber stopper.
Note: The "fill" hole part of the rubber stopper is not open
and would have to be opened if you want to add the
"fill" function. After the tank is full, this tube would
have to have a stopper put in to prevent fuel from
leaking out.
Note: Take note of the orientation of the tubes in the fuel
tank stopper. The portion of the stopper with the
"bump" is the front (facing outward), the smooth
surface is the rear (inside the tank) of the stopper.
Also note that the stopper fits over the outside of the
tank neck.
Step 5. Slide the two black plastic caps over the aluminum
tubes as shown, noting the orientation of the caps. The small
inside cap and the "bumps" face away from the black rubber
stopper. The large outside cap and the "bump" go away from the
black rubber stopper.
Step 6. Locate the silicone fuel tubing and the metal clunk.
Insert the fuel clunk into one end of the fuel tubing. This
assembly will be used for the fuel pickup inside the fuel tank.
Step 7. Install the open end of the fuel tubing on the shorter
aluminum tubing.
