6.2.3 Fuel Pickup
Description: The fuel pickup serves to extract the fuel
and to separate any bubbles that may be present in the
fuel. It must on no account be replaced with normal "T"
fittings. Owing to the high flow velocity prevailing in the
branch pieces of normal ''T" fittings, there is an in·
creased danger of gas bubbles being fed to the meter·
ing pump.
Note: The fuel tank must be sufficiently ventilated (e.g.
at the filler cap).

6.2.4 Fuel Filter
Description: The filter may be installed in the fuel intake
line between tank and metering pump. If the fuel
is likely to be severely contaminated. the filter must be
retrofitted.

replace filter completely (only Webasto filter.
order no. 487 171 to be used. see Installation Instructions

6.2.5 Tank Extracting Device
Description: The tank extracting device serves to draw
fuel from the fuel tank. It must be installed as close to
the tank as possible and leak-proof connection of the
fuel line must be ensured.
The distance existing between the end of the tube and
the bottom of the tank serves to prevent dirt and water
from being drawn in from the tank bottom.
