Safety precautions when working on the 
fuel supply system 

 

  

  

CAUTION!

 

  

  

When performing repair work, especially due 
to the confined conditions in the engine 
compartment, pay attention to the following:

 

  

  

 

Route all types of lines (e.g. for fuel, 
hydraulics, EVAP system, coolant, 
refrigerant, brake fluid and vacuum) as well 
as electrical wiring so that the original 
positions are restored.

 

  

  

 

Make sure sufficient clearance to all moving 
or hot components.

 

  

   When removing and installing the fuel gauge 

sender or fuel pump (fuel delivery unit) from a full 
or partly full fuel tank the following must be 
observed:  

  

  

WARNING!

 

  

  

Fuel supply lines are under pressure! Before 
removing from hose connections, wrap a 
cloth around the connection. Then release 
pressure by carefully pulling hose off

 Before commencing work, switch on exhaust 

extraction system and place an extraction hose 
close to sender opening in the fuel tank to 
extract escaping fuel fumes. If no exhaust 
extraction system is available, a radial fan with 
a displacement greater than 15 m

/h can be 

used (as long as motor is not in air flow).

  

  

 Prevent skin contact with fuel! Wear fuel

resistant gloves! 

    

 For safety reasons, fuse No. 28 must be 

removed from fuse holder before opening fuel

Rules for cleanliness 

 

  

   When working on the fuel supply/injection 

system, pay careful attention to the following 5 
rules:  

  

  

 Thoroughly clean all unions and the adjacent 

areas before disconnecting. 

  

  

 Place parts that have been removed on a clean 

surface and cover. Do not use fluffy cloths! 

  

  

 Carefully cover opened components or seal, if 

the repair cannot be carried out immediately. 

  

  

 Only install clean components: Only unpack 

replacement parts immediately prior to 
installation. Do not use parts that have been 
stored loose (e.g. in tool boxes etc.). 

  

  

 When the system is open: Do not work with 

compressed air if this can be avoided. Do not 
move vehicle unless absolutely necessary.
