Safety precautions when working on
fuel supply system
Caution
When doing any repair work, especially in the engine compart‐
ment, pay attention to the following due to the cramped condi‐
tions:
♦ Route all the various lines (e.g. for fuel, hydraulics, acti‐
vated charcoal filter system, coolant, refrigerant, brake
fluid and vacuum) and electrical wiring in their original po‐
sitions.
♦ To avoid damage to lines, ensure sufficient clearance to
all moving or hot components.
♦ For safety reasons, fuse nos. -13- and -14- -arrows- must be
removed from the fuse holder before opening the fuel system.
Otherwise, the fuel pump could be activated by the driver's
door contact switch.
♦ Fuse nos. 13 and 14 are located in the E-box fuse holder in
the left plenum chamber.
When removing and installing fuel gauge sender or fuel pump
(fuel delivery unit) from a full or partly full fuel tank, observe the
following:
♦ Even before work commences, the extraction hose of an ac‐
tivated fume extraction system has to be placed in the vicinity
of the assembly opening of the fuel tank to trap any escaping
fumes. If no exhaust gas extraction system is available, a ra‐
3
dial fan with a displacement greater than 15 m /h can be used
providing that motor is not in air flow.
♦ Prevent skin contact with fuel! Wear fuel-resistant gloves!
