Fit the fuel tap and main fuel line
Remove the lever from the fuel tap and set it aside.
Mark a position on the left-hand side of the centre
console 50mm in front of the base of the armrest and
30mm below the forward section of the console as
shown at right:
Drill a 16mm hole at that position.
Working through the access hole in the right-hand
side of the console, hold the fuel tap in position
against the inside of the left-hand side of the console
and mark the positions for the alignment pin and
screw holes, which will be visible through the fibreglass, then remove the fuel tap and drill
the holes. Pre-fit the fuel tap with the two screws and then remove the tap and set it aside.
Cut a length of blue fuel hose of sufficient length to reach from the fuel tap to a position about
300mm aft of the electric fuel pump (under the rear cabin step), and a length of black fuel
hose of sufficient length to reach from the fuel tap down along the floor and back up to the
firewall fitting plus 100mm.
Fit both fuel hoses to the fuel tap and secure with the
supplied hose clips, first making sure that the flow
arrow on the face of the fuel tap is facing towards the
black fuel line.
Place a length of
fuel line sheathing
over the black fuel
line and secure with
lock wire to the boss on the fuel tap as shown at right.
Fit the fuel line and tap assembly: cover the ends of both
fuel lines to prevent foreign objects from entering by using
masking tape over the ends and then insert the blue fuel line
end into the console through the access hole in the right-
hand side and feed the blue fuel line down and back towards the rear of the fuselage and into
the lower longitudinal rib along the rear floor.
Keep feeding the fuel line back until it can be seen in the hole in the lower longitudinal rib
near the electric fuel pump under the rear cabin step, then, using a length of wire with a hook
in one end, lift the fuel line out of the lower longitudinal rib and run it past the electric fuel
pump. Keep feeding the fuel line back until the end of the black fuel line can be inserted into
the access hole in the console and then feed the black fuel line down and forwards until it can
be lifted out of the hole in the forward section of the lower console behind the rudder pedals.
Using a length of wire with a hook in one end, reach down into the console and lift the fuel
line assembly and move the fuel tap into position. Mount the fuel tap and secure to the
console with the two screws. Cut the end of the blue fuel line to the correct length and connect
it to the electric fuel pump with a supplied hose clip.
Cut the black fuel line and sheath to length to reach the firewall fitting. Cover the open end of
the fuel line to prevent dust or dirt from entering the fuel system. The fuel line will be
connected to the firewall fitting after the upholstery has been fitted.
