The engine / mount assembly can now be attached to the firewall using the M4 x 25
machine screws supplied in the kit. These screws must be secured with a drop of
UHU thread-lock fluid to prevent them working loose.
At this point the silencer can be mounted on the engine using the screws supplied.
Assembling and installing the fueltank
Cut a piece of fuel tubing and push it onto the fueltank clunk pick-up. Push the free
end of the fuel tubing onto the straight tube in the fueltank stopper, and check that
the pick-up will be able to move freely inside the tank
without
binding or jamming
when the stopper is in place. Push the tank stopper, complete with pick-up and pre-
formed tubes, into the throat of the fueltank. Note that one tube must face down (for
filling the tank). The tube pointing up acts as the overflow when refuelling, and is
connected to the pressure nipple on the silencer prior to flying. Mark the three fuel
lines which exit the tank stopper (fuel feed, filler tube, pressure line). Push the
stopper into and over the throat of the tank and tighten the cross-point screw to
clamp it in place. It is essential to tighten the screw to the point where the tank is
completely sealed.
The fueltank can now be installed in the tank compartment immediately aft of the
firewall. Pack foam rubber round it to absorb vibration and prevent it shifting in flight.
