The "Pressure Line" is connected to the muffler of your
engine and serves to bring engine pressure into the tank
to help force fuel out the fuel line into the engine. It also
serves as a fuel overflow vent when topping the tank up
with fuel.
The "Fuel Line" will supply
fuel to the engine and
allow you to fill the tank up

Trial fit the tank
by inserting it from within
the fuselage radio
compartment, stopper
end first with the metal
tubes pointing up and
pushing the tank gently
forward until the metal
tubes and stopper pass
through the firewall.
Adjust the angle of the
metal tubes so that they
still point upwards and
clear the firewall with
sufficient clearance to
allow you to push the
fuel tubing on to and
over the metal tubes.

When you are
satisfied with the fit of the tank and the metal tubing,
we suggest also trial fitting your engine and ensuring
that the tank metal tubing clears the back of the
engine with sufficient clearance.

Remove the tank and place about 50 mm (2
in.) of medium tubing over the metal tubes so that the
tubing temporarily joins the metal tubes and seals
them off against dust, debris and sealant.
You will temporarily reinstall the tank again in Step
4.4 after locating the battery pack and then finally
seal the tank into position in Step 8.2 after balancing
the aircraft and getting the CG right.
