Step 8
Insert the stopper assembly into the fuel tank. Make sure the
vent line faces to the top of the tank as shown.
Step 9
Use a #1 Phillips screwdriver to tighten the 3mm x 20mm
machine screw that secures the stopper in the tank. Don’t
over-tighten the screw as you could damage the fuel tank. It
needs to be tight enough to create a seal between the tank
and stopper.
Step 10
Slide the fuel tubing on the brass tubes outside the tank.
Slide the red line on the vent line and the green line on the
line from the clunk.
Important
: Use the two yellow tubes for the gas
installation. Make sure to wire the tubes to the brass
tubes so they don’t slip off in flight.
Step 11
Slide the fuel tank into the fuselage. Guide the lines from the
tank through the hole in the firewall. Use two rubber bands
to secure the tank in the fuselage.
Step 12
Connect the lines from the tank to the engine and muffler.
The vent line will connect to the muffler and the line from the
clunk to the carburetor. We used a fuel dot and a T-fitting on
the line to the carburetor so the tank can be fueled without
removing the cowling.
