above the fuel level and stop the fuel flow. Remember which
is the fuel pick-up, vent and fill tubes. You can mark the
tubes with a Top Flite Panel Line Pen if you wish.
❏
11. Cut the fuel line (not included), in three 9" [228mm]
length sections. Install the three sections of fuel line on the
three fuel tank tubes. Mark the fuel lines so that you know
what each one is for. Install the fuel tank in place. Use a #64
rubber band to hold it in place. Make sure the fuel tubes exit
freely through one of the access holes in the front of the
fuselage.
❏
12. Connect the carburetor line to the fuel nipple at the
engine’s needle valve. Connect the muffler line to the
pressure fitting on the muffler. Use a Great Planes
Aluminum Fuel Line Plug (GPMQ4166) to plug the fill fuel
line. If you wish, you could install a Great Planes Easy
Fueler Valve for glow engines (GPMQ4160) instead of the
third (fill) line in the tank.
Note: The hardware necessary for the installation of the gas
engine is not supplied in this kit. Please refer to the front of
the manual for a list of required parts.
Note: The gas engine you use needs to be installed in a way
so that the drive washer is located 7" [178mm] from the
firewall box, just like the glow engine. Use spacers if you
need to in order to achieve this. The Fuji engine shown here
does not need any spacers.
❏
1. Find the engine mount template provided with your
engine. Use spray adhesive or tape to temporarily attach the
template to the firewall. Align the template using the vertical
and horizontal lines of the firewall. Drill 1/4" [6.4mm] holes
through the firewall at the marks.
❏
2. Make sure you make any clearance holes needed in
the firewall for the engine you use. Remove the engine
template and fuelproof the holes with thinned down epoxy.
❏
3. Install the throttle linkage from the carburetor arm to
the 90° nylon bellcrank. Use #8 flat washers as spacers to
separate the bellcrank from the engine. Make sure the
linkage can rotate freely and that it does not bind.
