Push the prepared fueltank into the fuselage and thread the fuel lines through the
hole in the firewall. Glue the tank support behind the fueltank to hold it in place.
Connecting the fuel lines
Connect the silicone fuel line running from the clunk pick-up to the carburettor fuel
nipple, and the tube from the overflow to the pressure nipple on the silencer.
The fuel tube marked as the filler should be routed out of the cowl so that the tank
can be filled through it. Seal the tube before each flight using a sealing nipple, Order
No. 140.
Please note that fuel will run out of the overflow (pressure) line when the tank is full.
Take care not to fill the silencer with fuel.
The cowl can now be fitted, along with the propeller and the spinner. It is important to
check at regular intervals that the propeller retaining screw or nut is still tight.
The next step is to cut or file out openings in the cowl to clear the cylinder head, the
silencer and the needle valve; the position and extent of the openings vary according
to the engine you are using. Note that the needle valve must be extended with a
scrap piece of pushrod material, so that you can still adjust it with the cowl in place.
Attach the cowl to the fuselage using four pan-head self-tapping screws, as shown in
the photos.
