the fuel lines.

11. Drill two ¼" [6mm] holes in the bottom of the air
scoop as shown. The holes should be drilled at an angle
and through the top of the air scoop.

12. Install fuel lines onto the brass tubes from the
fuel tank. To route the fuel lines as will be shown here
you will need to use a 24" [610mm] length of tubing on
the fi ll and vent lines and a 6" [152mm] length on the
carburetor line.
❏
13. With the fuel lines installed on the fuel tank,
install the lines and tank into the fuselage. Make sure
the vent tube in the tank points toward the top of the
fuselage. Feed the lines into the holes you drilled. You
will fi nd it easier to route the fuel lines if you install a
long handled ball wrench through the holes and slide

wrench as a guide for feeding the lines through. Install
the metal fuel plug into the fuel line that is the fi ll line.

14. Locate the 24" [610mm] plastic outer pushrod
tube. Cut two pieces 6" [152mm] in length. Roughen the

tubes into the fuselage. Slide the tubes into the fi rewall
so the roughened end of the tube contacts the fi rewall.

alongside the fuselage. The tab in the tray notches
