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-

Power Distribution
The maintenance free 90 AH battery
in the X5 is mounted in the rear below
the spare tire and EHC compressor
unit. The battery box is formed of
molded plastic and the positioning of
the battery aids in weight distribution.
As with all BMW vehicles, the battery
is equipped with the BST on the pos-
itive battery cable.
Power distribution for the vehicle and
systems is through two fuse carriers
mounted in the right storage com-
partment in the rear and above the
glove box in the front.
The battery jump/charge point is
located in the engine compartment on
the left side of the fire wall.
