The values for the maximum pressure at the fuel extraction point are
shown in the table below.

NOTE
A fuel feed line can normally be identified by the fact that a fuel filter is
installed in it.
Fuel may only be taken from the return line using the special Webasto
fuel extractor (see Figure 8).
The fuel extractor must be fitted in such a way that any air or gas
bubbles are automatically discharged towards the tank (see Figure 8).
Air or gas bubbles may be produced in the vehicle's fuel line if there
are leaks in the carburettor or vehicle fuel pump or if the ambient
temperature is higher than the evaporation temperature of the fuel.
