4.1 Fuel Extraction
4.1.1 Standpipe Installation Position
The installation position of the fuel extractor is
shown in Figure 23 and depends on the
relevant vehicle-specific installation conditions.
General instructions The following details are
supplied in the installation documentation for
the specific vehicle:
- Position of the hole in the tank fitting
- Cut the fuel extractor to length
- Shape and bend the fuel extractor
- Vehicle-specific installation instructions
If you do not have any installation documentation for the specific vehicle, find a suitable position in the tank
fitting. The fuel extractor must end 5 - 8 mm above the base of the tank after it has been shaped and cut to
length. It must not interfere with the function and stability of the tank fitting.
IMPORTANT To ensure that the tank fitting it perfectly sealed, its surface areas at the top and bottom, near the
fuel extractor, must be parallel to each other and completely flat (no embossing, labelling, etc.). The parts must
be clean and must not come into contact with fuel or grease before installation. Do not lose the sealing ring in
the fuel extractor's groove.
NOTE These binding installation instructions apply to the above fuel extractor as long as technical modifications
to the vehicle do not adversely affect the installation. Depending on the version of and equipment in the vehicle
it may be necessary to change these installation instructions. In any event, however, you must comply with the
appropriate technical rules and regulations for the installation work. Failure to follow these installation
instructions and their content will result in the refusal of all liability on the part of Webasto. The same also
applies to repairs not carried out properly or using parts other than genuine spare parts
