The mating surface of the tank extracting device must he clean, even and
burr-free.
When fitting the tank extracting device in the fuel delivery unit, make sure
the standpipe is correctly installed. The standpipe must not affect the
function of the fuel delivery unit, including the fuel gauge, in any operating
state.
The length of the standpipe must be selected so that when installed, a
minimum distance of 10 mm above the tank bottom or 20 above the bottom
of the fuel delivery unit is guaranteed.
The safety measures specified by the vehicle manufacturer and the
corresponding torques must be observed.
6.4. Integration via the fuel tank drain screw
The fuel can also be extracted via the fuel tank drain screw (see Fig. 10).
This separate fuel extraction precludes any effect of pressure.
