FUEL FILTER (FOR DIESEL)
Draining water from the fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in its
bottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position.
If this warning light illuminates,
take your car to an authorised
HYUNDAI dealer and have
drain the water and checked
the system.
Extracting air from the fuel filter
If you drive until you have no fuel left or if
you replace the fuel filter, be sure to
extract air from the fuel system as it
makes it difficult to start the engine.
1. Pump up and down(1) approximately
50 times until the pump is hard.
2. Extract air from the fuel filter by remov-
ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
3. Pump up and down(1) approximately
15 times.
4. Extract air from the fuel filter by remov-
ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
5. Pump up and down(1) approximately 5
times.
✽NOTICE
• Use cloths when you extract air so that
the fuel is not sprayed around.
• Clean the fuel around the fuel filter or
the injection pump before starting the
engine to prevent fire.
• Finally, check each part if the fuel is
leaking.
Fuel filter cartridge replacement
✽NOTICE
When replacing the fuel filter cartridge,
use HYUNDAI genuine parts.
CAUTION
If the water accumulated in the fuel
filter is not drained, damages to the
major parts such as the fuel system
can be caused by water permeation
in the fuel filter.
