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 in-
take line between tank and metering pump. If the fuel
is likely
to
be
severely contaminated. the filter must
be
retrofitted.
Check: Observe direction of
flow.
In
the case of con-
tamination, replace filter completely (only Webasto fil-
ter, order
no.

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.
