K7M engine
Fit the 0 ; 10 bars pressure gauge and the hose
Mot. 1311-01.
Shunt terminals (3) and (5) on the fuel pump relay
located in the engine fuse box (see diagram on
page 13-2).
The pressure should be 3 bars ± 0.2.
When a vacuum of 500 mbars is applied to the
pressure regulator, the fuel pressure should be
2.5 bars ± 0.2.
CHECKING THE PUMP SAFETY VALVE (under the
same conditions as previously)
Shunt terminals (3) and (5) of the fuel pump relay
(see diagram on page 13-2).
When the fuel return pipe is clamped briefly, the
pressure should stabilise between 4.5 and 7.5
bars.

CHECKING THE FUEL SUPPLY PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 1311-01 Fuel pressure test kit (with 0 ;+
10 bars pressure gauge included)
99217R1
Disconnect the rear fuel pipe.
Fit the three way valve (1) from tool Mot. 1311-01
and connect the 0 ; + 10 bars pressure gauge.
Shunt terminals (3) and (5) of the fuel pump relay
located in the engine fuse box.
The pressure should be 3 bars ± 0.2.When a vacuum of 500 mbars is applied to the
fuel pressure regulator, the pressure should be
2.5 bars ± 0.2.
CHECKING THE PUMP SAFETY VALVE (under the
same conditions as previously)
Shunt terminals (3) and (5) of the fuel pump relay
(see diagram on page 13-2).
When the fuel return pipe is clamped briefly by
the two position valve, the pressure should
stabilise between 4.5 and 7.5 bars.

LOCATION
Principle of the electric heater
The heater has heated studs. They are ceramic,
made from barium titanate which has a positive
temperature coefficient, meaning that its
resistance increases as its temperature increases.

2Electric heater
3Hand priming unit
The electric diesel fuel heater and the thermostat
are integral in the head of the filter.
