EDGE 540. Instruction Manual.

Important: When the stopper assembly is
installed in the tank, the top of the vent
tube should rest just below the top surface
of the tank. It should not touch the top of
the tank.
4) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using a
modeling knife. If flashing is present, make
sure none falls into the tank.
5) With the stopper assembly in place,
the weighted pick up should rest away from
the rear of the tank and move freely inside the
tank. The top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
Attach the silicone fuel and pressure pipes
to the tank. The lower pipe is the ‘feed’ and the
upper two the ‘pressure and fill’. The fill pipe is
the next pipe.
You should mark which tube is the
vent and which is the fuel pickup when you
attach fuel tubing to the tubes in the
stopper. Once the tank is installed inside
the fuselage, it may be difficult to determine
which is which.
6) When satisfied with the alignment of
the stopper assembly tighten the 3mm x 20mm
machine screw until the rubber stopper ex-
pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.
Blow through one of the lines to en-
sure the fuel lines have not become kinked
inside the fuel tank compartment. Air
should flow through easily.
MOUNTING THE ENGINE.
1) Install the pushrod housing through the
predrilled hole in the firewall and into the servo
compartment. The pushrod housing should
protrude 1/4" out past the front of the firewall.
Make a Z-Bend 1/4" from one end of the
plain wire pushrod.
