General
WARNING-
Never run the engine in tile work area unless it is well-ven-
tilated. The exhaust should be vented to the outside. Car-
bon monoxide (CO) in exhaust kills.
Remove all neckties,
scarfs, loose clothing, or jewelry
when working near a running engine or power tools.
Tuck in shirts. Tie long hair and secure it under a cap.
Severe injury can result from these things being
caugiit
in rotating parts.
Remove rings, watches, and bracelets. Aside from the
dangers of moving parts, metallic jewelry conducts
electricity and may cause shorts, sparks, burns, or
damage to the electricalsystem when accidentally con-
tacting the battery or other electrical terminals.
Disconnect the battery negative
(-) cable whenever
working on or near the fuel system or anything that is
electrically powered. Accidental electrical contact may
damage the electrical system or cause a fire.
Fuelis highly flammable. When working around fuel, do
not
smoke or work near heaters or other fire hazards.
Keep an approved fire extinguisher handy.
The fuel system is designed to retain pressure even
when the ignition is off When worlcing with the
fuelsys-
tem, loosen the fuel lines slowly to allow the residual
pressure to dissipate gradually. Take precautions to
avoid spraying fuel.
. Illuminate the worlc area adequately and safely Use a
portable safety light for worlcing inside or under the car.
A fluorescent type
light is best because it gives off less
heat. If using a light with a normal incandescent bulb,
use rough service bulbs to avoid
breakage. The hot fil-
ament of an accidentally broken bulb can ignite spilled
fuel or oil.
Keep sparks, lighted matches, and any open flame
away from the top of the battery. Hydrogen gas
emitted
by the battery is highly flammable. Any nearby source
of ignition may cause the battery to explode.
Never lay
tools or parts in the engine compartment or
on top of the battery. They may
fallinto confinedspaces
and be difficult to retrieve, become caught in belts or
other rotating parts when the engine is started, or
cause electrical shorts and damage to the electrical
system.

Basic tool requirements
The basic hand tools described below can be used to accom-
plish most of the simple maintenance and repair tasks.
Screwdrivers
4 The common flat-blade type, Phillips type, and TorxO type
screwdrivers will handle almost all screws used on
BMWs.
Two or three different sizes of each type will be required,
since a screwdriver of the wrong size will damage the screw
head.
Wrenches
4 Wrenches come in different styles, including open-end. 12
point box-end,
6 point box-end and flare nut. The basic open-
end wrench is the most widely used, but grips on only two
sides. The box-end wrench has better grip on all six sides of
a nut or bolt.
A 12 point box-end can loosen a nut or bolt where there is less
room for movement, while
a 6 point box-end provides better
grip. For hex fasteners on fluid lines, like brake lines and fuel
lines, a flare-nut wrench offers the advantages of a box-end
wrench with a slot that allows it to fit over the line.
The combination wrench is the most universal. It has one
open-end and one box-end. 10 mm and 13 mm wrenches are
the most common sizes needed.
A more complete set of
wrenches would include
6 mm through 19 mm sizes.

1 Maintenance
- When replacing fuel filter:
Use appropriate hose clamping device to clamp off filter
inlet and outlet hoses to lessen fuel spillage.
Loosen center clamping bracket and hose clamps on
either end of filter.
Note arrow or markings indicating direction of flow on
new filter.
Install new filter using new hose clamps
- Drain fuel filter from inlet side into a container and inspect
drained fuel.
Checlc for rust, moisture and contamination.
I - I < If fuel filter is equipped with fuel pressure regulator:
I 2 / Remove vacuum hose (1)
Pull out locking clip (2).
- Remove fuel pressure regulator (3).
Install pressure regulator in new filter.
Clean thoroughly around the filler connections before
removing them.
After assembly, check filter connections carefully for
I
I lealcs before installing cover.
NOTE- ~-
Additional informarion about the fuel filler assembly is in 160
Fuel Tank and Fuel Pump.
Fuel tank and fuel lines, inspecting
lnspectthe fuel tank, fuel lines, and fuel system fordamage or
lealts. Checlc for fuel lealts in the engine compartment or fuel
odors in the passenger compartment. Check for any evapora-
tive emissions hoses that may have become disconnected,
checking carefully at charcoal canister and evaporative emis-
sions purge system. See
130 Fuel Injection and 160 Fuel
Tankand Fuel Pump for component locations and additional
information.
WARNING-
When checlcing for fuel leal(s, the engine must be cold. A hot
exhaust manifold or exhaust system could cause the fuel to
ignite or explode causing serious personal injury Ventilate
the work area and clean up spilled fuel immediately.
