the hatch. Place a piece of scrap foam between the top of the tank and the side of the
fuselage to hold the tank in this position.
Cut a piece of scrap balsa block to act as a spacer between the front of the tank and the
former. Make sure you can access the forward wing spar mounting bolts, and then attach
the spacer block to the front former with a drop of CA.

When you are happy with the position of the tank, test fit the hatch and check for clearance.
If everything checks out, glue the Velcro to the slots routed in the rail with 5-minute epoxy.
Also apply epoxy to the point where the Velcro strap meets the side of the fuselage, being
careful not to glue the tank to the strap. This will keep the tank from shifting.
Repeat all steps for the other saddle tank.
Check the fuel lines for nicks and cuts as you proceed through the next steps.
Connect two pieces of fuel tubing approximately 180 mm long to the fuel pickup tubes in
each saddle tank and bring them together with a “Y” fitting just above the intakes.
Repeat this process for the vent tubes in the saddle tanks.
Run a length of fuel tubing from the “Y” fitting connected to the fuel pickup tubes to the vent
tube of the main center tank.
Attach a length of tubing to the “Y” fitting connected to the vent tubes on the saddle tanks.
The vent fitting will be positioned in the forward fuselage … a pigtail of approximately 200
mm extending past the forward former should be sufficient.
Connect a length of tubing that will run to the fuel pump to the fuel pickup tube on the main
center tank.
Wire tie all connections at this time
If you use plastic wire ties to bind the fuel tubes together for a neater installation, make sure
not to over-tighten and pinch down on the flexible fuel tubing.
This completes the fuel system.
