The X5 uses a two piece lug bolt that incorporates a spacer wash-
er and features anti-corrosion coating. The tightening torque on the
lug bolts is 130Nm +/- 10Nm. Advantages of using the spacer
washer include:
• Longer expansion length for the bolt.
• A better fit to the wheel
• The spacer washer is fixed to the wheel when tightening and
the lug bolt turns relative to it.

Fuel System Supply
The fuel tank is constructed from molded plastic and is mounted under the rear seat and
extends along the left side of the vehicle. It is the saddle tank design with a siphon jet pump
in the right side to transfer fuel to the left side where the fuel pump is mounted.
The fuel filter/pressure regulator is
mounted in front of the tank along with
the charcoal canister. The components
are covered by a plastic plate to protect
them when driving off-road.
The liquid/vapor separator is mounted
on the right side up in the wheel arch
opening next to the filler neck.
The Leak Diagnosis Pump (LDP) is
mounted in the left rear side wheel arch
opening behind the wheel housing
cover. Operation of the LDP will be cov-
