played on the R-Touch in millibars (mbar). The fuel pressure increases for some
time and remains constant at about 3500 mbar. Thus, the fuel system is vented.

has stopped, set the option in the "Service fuel filter" line to "OFF".

(4) on the fuel supply control block (5) 45° forward (vertical position).
