Bleeding the Fuel System

A completely bled fuel system is
imperative for perfect engine oper­
ation. During operation, the system
is continuously bled via the over­
flow line.
The entire system must be bled
when the car has been driven until
the fuel tank was completely
emptied.
After refueling, start the engine,
engaging the starter for about
20 seconds until all the trapped air
has been evacuated.
With a poorly charged battery the
system must be bled manually.
Operate the prim er pump until the
injection pump overflow valve
opens (rattling noise audible).
Disengage prim er pump handle
prior to operating it (turn counter­
clockwise). Retighten after use.
Practical Hints

Turning off Engine Manually

If the engine continues operating
in steering lock position " 0" , open
