Components :
a) Fuel Pre-Filter Cum Sedimentor :
The pre-filter cum sedimentor is a part of the
filtration system. It is fitted in the fuel feed system
to filter the water present in the fuel. It can store
water up to 120cc. The sensor fitted in the
sedimentor gets triggered once the water level
approaches its maximum limit. This trigger is
displayed as a warning in the instrument panel.
For more details on the sensor refer EMS Section
in this group.
For removal and re-fitment procedure refer Engine
On-vehicle repairs in this section.
Water in Fuel Indicator :
b) Fuel Filter :
The Fuel filter is fitted as a second filtering step in
the fuel feed system. It is mainly used to filter out
particles that are present in the fuel.
For removal and re-fitment refer Engine on vehicle
repairs in this section.
CAUTION
The fuel filter and fuel sedimentor should
be replaced as recommended in the
service schedule. If this is not done, it may
result in impurities or particles entering the
High pressure system causing damage to
the Fuel Injection components.
c) Priming Pump :
Priming pump is provided in the low pressure line
just before the fuel filter. It is used to prime the
fuel feed system with fuel. This is done in order to
avoid air lock in the system. The advantage is that
the fuel lines need not be loosened or dis-
connected to bleed the system. Priming can be
done by pressing and releasing the bulge
repeatedly till it is filled with fuel.
