Safety precautions when carrying
out work on fuel supply system
Important!
Fuel system is pressurized! Place cleaning cloth
around the connection point before opening the
system. Then, release the pressure by carefully
detaching the connection point.
Pay attention to the following points when
removing and installing the fuel gauge sender
or the fuel pump (fuel delivery unit) from the fuel
tank:
♦ Fuel tank should be not more than 2/3 filled.
♦ The extraction hose of an operating exhaust
gas extraction system should be positioned
close to the assembly opening of the fuel tank
for extracting the fuel gases which are
released even before commencing the work.
If no exhaust gas extraction system is
available, a radial fan (engine outside of air
flow) with a delivery volume of more than 15
m 3 /h may be used.
♦ Ensure fuel does not come into contact with
your skin! Wear fuel-resistant gloves!

Rules for cleanliness

Pay careful attention to the following „5 rules"
for cleanliness when carrying out work on the
fuel supply/fuel injection system:
♦ Thoroughly clean connection points and the
surrounding area before disconnecting.
♦ Place removed parts down on a clean
surface and cover over. Do not use fluffing
cloths!
♦ Carefully cover over or seal opened parts if
repairs are not carried out immediately.

Do not remove replacement parts from their
wrapping until just before installing.

unwrapped (e.g. in tool boxes etc.).
♦ If the system is opened:
Avoid working with compressed air, if
possible.
