Put a couple of cable ties around the fuel hose under the floor to keep them together
Stick some placement pegs on the floor of the cabin and fix the fuel lines to them using
cable ties.
Preparing the fuel lines to be connected to the fuel tanks in the wing:
The fuel lines going to the wings are secured with plastic straps, a washer and a rivet.
The first rivet is placed 200 mm from the cabin's ceiling, followed by another 200 mm
down, then another 200 mm down and the last one 170 mm down, as shown in the
picture below. They are all spaced about 30 mm from the edge of the cockpit and mount
into the bulkhead straight the pilot's shoulders.
Use a 4mm rivet size and drill a 4.2 mm drill. The structure has a Kevlar base and if you
drill say a 4mm hole it closes slightly after you remove the drill. This makes it harder to
get the rivet in, so that’s why we drill 4.2mm.
Lastly, fix a fuel valve to the installed bracket just as done before. The valve handle
should open downwards. Use Loctite 577, heat the tube ends and tighten with cable ties.
