4.8 Fuel Filler Cap
The fuel filler cap is a 'screw on' type, with an integrated tightening torque limiting mechanism. W hen installing the fuel
filler cap, tighten it until a ratcheting (clicking) sound is audible, indicating the fuel filler cap is properly tightened. Th e fuel
filler cap is tethered to the fuel filler pocket.
Remove
The fuel filler cap requires a quarter of a turn anticlockwise to be removed.
Vacuum and pressure valves are built into the fuel filler cap
which regulate the pressure in the fuel tank and prevent fuel
tank and system damage.
Inspection
Inspect the fuel filler cap and seal for any signs of damage.
Replace the fuel filler cap if found to be defective.
1 Pressure Valve
2 Vacuum Valve
3 Seal Ring

A replacement fuel filler cap must be the
same type as the original. The fuel filler cap
pressure and vacuum valves are specific to a
particular application and must be replaced
with the same type or fuel system damage
may occur.
Figure 6C – 36

If the fuel filler cap needs replacing, use only
a 'screw on' fuel tank filler cap with an
integrated tightening torque limiting
mechanism. Failure to use the correct fuel
tank filler cap can result in a serious
malfunction of the emission control or fuel
system.
1 Untwist and remove the fuel filler cap (2) from the fuel filler neck opening.
2 Cover the fuel filler opening with a suitable material to prevent foreign objects from entering the fuel tank.
3 To remove the fuel filler cap tether line use a flat- bladed screwdriver to prise the tether line fastener (2)
from it’s mounting hole.
NOTE
Check the fuel filler cap for serviceability and
replace if required.
