Now push the tank stopper, complete with pick-up and pre-formed tubes, into the
throat of the fueltank, and tighten the cross-point screw to clamp the stopper in place. It
is essential to tighten the screw to the point where the tank is completely sealed. You
can check this by holding the tank under water and blowing hard into the fuel tubes:
any air bubbles indicate a leak which must be eliminated.
Connect a further length of fuel tubing to each stub tube projecting from the fueltank
stopper.
Mark the individual fuel lines so that you can identify which is the fuel feed (to the
engine), which is the overflow, and which is the filler line.
The tank support should now be glued in the fuselage, as shown in the photo.
Ensure that the support rests against the firewall, and is located centrally. Allow the
glued joint to set hard before installing the fueltank on it.
