Great Planes Cessna 182 Skylane 40 ARF - GPMA1228 - Manual (Page 18)

❏
1. Push one short aluminum tube and one long aluminum
tube through the rubber stopper until 1/2" [13mm] of the
tubes protrudes from the front of the stopper. Slide the large
cap onto the front of the stopper, and the small cap onto the
back. Insert the stopper screw into the center hole in the
front cap, then thread it through the stopper into the aft
stopper cap. Just start the threads in the aft cap or you won’t
be able to insert the stopper into the tank.
❏
2. Push one end of the silicone pickup tube all the way
onto the clunk, and the other end all the way onto the short
aluminum tube. Bend the long aluminum (vent) tube upward
at about a 45º angle, being careful not to kink the tube.
❏
3. Test fit the stopper into the fuel tank. The seam around
the tank should be vertical. By holding the tank up to the
light you will be able to see where the vent tube is, in relation
to the top of the tank. If necessary, bend the vent tube to
position it about 1/8" [3mm] below the top of the tank. When
satisfied with the fit, make sure the stopper is fully seated in
the fuel tank. Tighten the stopper screw until the plastic cap
is indented about 1/16" [1.5mm]. Doing so will lock the
stopper into position. Check the clunk and pickup tube to
make sure they move freely in the tank without binding.
Mark the vent and clunk lines on the stopper so they can be
identified when the tank is installed.
❏
4. Cut two 8" [203mm] pieces of medium fuel tubing and
attach them to the vent and clunk lines on the fuel tank.
Slide the fuel tank into position, guiding the tubes through
the hole in the firewall. Secure the position of the fuel tank
as shown in the photo to prevent movement during flight.
(The wood for securing the fuel tank is not included.)
❏
5. Remove the covering from the fuselage in the location
of the muffler shield. Test fit the shield into position. Trace
around the shield, and remove the covering from the
fuselage under the shield. Use medium CA to glue the shield
into position.
❏
6. Install the muffler for your particular engine. The location
of the muffler shield is suitable for most engines. If your particular
muffler does not line up, you may need to use an optional
muffler. Attach the vent line to the muffler and the clunk line
to the carburetor after cutting them to the proper length.
