Fuel Tank Assembly And Installation - Horizon Hobby Pitts S-2B 50–60cc Manuel D'utilisation

137. Use side cutters to remove the arms that face up, forward
and rearward. Install the pushrod connector in the servo arm.
Use a toothpick to apply a drop of thin CA to secure the nut.
 Use the instructions included with the engine for details
regarding the position of the pushrod connector.
138. Secure the servo arm to the servo using the hardware
included with the servo.
139. Use 30-minute epoxy to glue the servo tray in the fuselage.
Allow the epoxy to fully cure before sliding the pushrod
through the connector.
140. Close the carburetor and use the radio system to move
the servo to the close position. Secure the pushrod in the
connector using the M3 setscrew and 2mm hex wrench.
Apply thread lock on the setscrew to prevent it from vibrating
loose. Check the operation of the carburetor to make so it
opens and closes as outlined in the engine instructions.

to have a slight barb, similar to that on the front of the
stopper. Bend one tube so if will face toward the top of the
tank when installed.

142. Slide the fuel tubing into position.
143. Attach the clunk to the fuel line. The distance from the rear
aluminum plate to the end of the stopper will be 5
(140mm). Use a small piece of wire to secure the tubing so it
does not slide off the tube or clunk.
 We recommend using a filtered clunk for the
engine, and a second clunk to fuel the aircraft.
144. Install the stopper in the tank. Make sure the clunk(s) can
move freely inside the tank. Reposition the tubes in the
stopper or trim the fuel tubing if necessary. Tighten the screw
in the stopper using a #2 Phillips screwdriver secure the
stopper in the tank.
 Overtightening the stopper can potentially split the fuel tank.
145. Secure fuel tubing to the outside of the tank using tie wraps.
Trim the tie wraps so they don't interfere with the installation
of the fuel tank.
146. Secure the fuel tank in the fuselage using hook and loop
straps. Use a piece of thin foam rubber between the tank
and fuel tank tray to prevent it from sliding on the tray during
extreme maneuvers.
