14.2 FUEL LINES
14.2.1 DESCRIPTION
Flexible fuel lines are used in Jabiru aircraft.
14.2.2 REMOVAL
Where required, fuel lines are removed be loosening the hose clamps and pulling the line off the
hose-tails.
In some cases it may be necessary to cut the lines off the hose tails due to lack of access, hard, tight
lines etc. Care must be taken that sufficient spare line remains to re-connect for assembly,
alternately a new line must be fitted.
14.2.3 INSPECTION
For aircraft with wing tanks:
-
Remove the header tank cover (the baggage shelf for J160 / J170 family aircraft and the sound
curtain at the rear of the cabin for J230 family aircraft).
-
Ensure there are no
U’s or inverted U’s in the lines.
-
Ensure line restraints are spaced at intervals no greater than 400mm (In some cases fuel lines
are bundled inside tubes which are Velcro-ed to the aircraft
– this is sufficient restraint.) If new
restraints are added, plastic line clips can be bonded to the aircraft structure. (Figure 157 refers).
Fasteners such as screws, which damage the structure, should not be used.

14.2.4 INSTALLATION
Care must be taken when re-routing lines to avoid bending the hose around too sharp a corner
– the
flexible hose used can crimp itself off if bent too sharply. If a sharp bend is unavoidable a spring may
be threaded over the line to prevent it crimping. Springs must be a snug fit on the hose & are
available from Jabiru Aircraft if required. Figure 157 refers.
Note that in some cases it may be necessary to shorten or lengthen lines
to prevent “U’s” or tight
bends.
For installation, reverse removal procedure given above.
