Electric fuel pump (24V)
The use of the electric pump is foreseen for certain applications
(where the engine has to be started at very low temperatures).
Assembly notes:
When the electric fuel pump is installed in a diesel engine, it is
necessary to:
1) Removethelterttedatthepumpintake(intakeside).
2) Inserttheprelterupstreamofthepump(intakeside).
3) The electric pump on the application must be at such a height
from the minimum tank level that it generates a maximum
pressure drop equal to a column of 500 mm of water.
4) Avoid running dry due to emptying of the intake pipeline, inserting
a non-return valve.
Features:
Pressure: 0.44 / 0.56 bars
Max capacity: 100 l/h

Injection pump
Theinjectionpumpofasimplied Q type has been designed by
LOMBARDINI for installation on engines of the CHD series.
The injection system includes three or four separate pumps
each of which feeds a cylinder.
Located on the crankcase at the level of the corresponding
cylinder, pumps are directly operated by the camshaft.
All high pressure tubes between injector and pump A feature the
same shape and dimensions.
Injection pump disassembly
Release the spring from the cap and remove the plunger.
Two pins keep the upper cap connected to the pump body; pry
with a tool between the pump body and the cap.
