3. Install the fuel tank in the airframe. Use only gasoline-safe fuel
lines and a gasoline safe fuel tank stopper. One line should go to
the carburetor and the other is to be used as a vent (a vent line is
simply an open ended fuel line from the fuel tank which exits the
engine compartment or the fuselage; most vent lines exit at the
bottom of the fi rewall).You can fi ll the tank by using the carburetor
line as fi ll line if you have access to it or install a third line to be
used as fi ll line. Installing a third line is the cleanest and easiest
way to add fuel. An alternative fueling set up is a 2-line system
with a T-fi tting approved for gasoline use. Be sure to use a fi ller
plug with either a 2 line or 3 line set-up.
