Bleeding and draining the fuel system
Bleeding, after refuelling a fuel system which
has been run dry, is performed the next time
the engine is started. Automatic continuous
bleeding takes place in the filter.
When the engine is started, the battery must
have sufficient charge to bleed the fuel sys-
tem.
Bleed the heated fuel prefilter with water sep-
arator on the vehicle before the fuel circuit on
the engine is bled by the starter motor. Use
the manual fuel pump integrated in the fuel
prefilter to do so.
