14.7 FUEL FILTERS
14.7.1 DESCRIPTION
The fuel filter is of the in-line type. It is located:
-
Inside the header tank enclosure behind the seats for J160 family models
-
Under the fuel tank for models equipped with a fuselage fuel tank.
-
Inside the removable fiberglass console joining the centre console to the firewall (between the
rudder pedals) for J200 family models.
-
Beside the header tank, inside the fuselage, aft of the sound curtain for J230 family aircraft.
14.7.2 FUEL FILTER REMOVAL & INSTALLATION
1.
Shut off the fuel on the tank side of the filter. This may require the fuel tap be turned off or that
the fuel system, wing tanks and header tanks be drained (where equipped). Alternatively fuel line
clamps (Figure 24) may be used to close the fuel lines so that the filter can be changed without
fuel leakage.
2.
Place a cloth beneath the filter to collect any fuel which may be split during removal of the filter.
3.
Disconnect the fuel lines at both ends of the filter.
4.
Remove filter.
5.
Reverse the preceding steps for installation. Ensure waste cloth is removed.
WARNING
Ensure tank vents are open (no vent covers fitted).
The fuel filter must only be installed in one direction. An arrow on the side of the filter marks the
fuel flow direction. Ensure this arrow is pointed towards the Firewall and Engine.
14.8 FUEL PUMPS
14.8.1 DESCRIPTION
The Primary Fuel Pump is located on the Starboard rear of the Engine. Refer to engine Maintenance
& Instruction Manual for details.
A secondary, electric fuel pump is also installed in all Jabiru Aircraft to assist the primary pump,
prevent vapor-lock and for redundancy.
14.8.2 SECONDARY FUEL PUMP REMOVAL & INSTALLATION
Shut off the fuel on the tank side of the pump. This may require the fuel tap be turned off or that the
fuel system, wing tanks and header tanks be drained (where equipped). Alternatively fuel line
clamps (Figure 24) may be used to close the fuel lines so that the pump can be changed without fuel
leakage.
Free the pump from its mounts
– undo the screws holding it in place. Note that in several models
this will require a second person outside the aircraft to hold the head of the screw while the nut is
loosened inside the cabin.
Disconnect the pumps electrical connections.
Place a cloth beneath the pump to collect any fuel which may be split during removal of the filter.
Disconnect the fuel lines at both ends of the pump.
Remove pump.
Remove the hose tail fittings from both ends of the pump. Clean the thread of the fittings for re-use.
Clean the threads of the hose tails and of the replacement pump using Aerostart or a volatile tool
cleaner (a type which does not leave a residue). If cure time is an issue use Loctite 7471 Cure
Accelerator on the parts before assembly.
Apply Loctite 262 to the mating threads; a bead the size of a match head should be applied to both
the male and female threads. Assemble.
