General Precautions |
EBS00GRC |
WARNING:
when replacing fuel line parts, be sure to observe the following.
●Put a “ CAUTION: FLAMMABLE” sign in workshop.
●Be sure to work in a well-ventilated area and furnish workshop with a CO2 fire extinguisher.
●Do not smoke while servicing fuel system, keep open flames and spark away from work area.
CAUTION:
● Before removing fuel line parts, carry out the following procedures.
– a) Put drained fuel in an explosion-proof container and put the lid on securely, keep the container in safe area.
– b) Release fuel pressure from fuel line. Refer to EC-58, "FUEL PRESSURE RELEASE" (QG engine models WITH EURO-OBD), EC-591, "FUEL PRESSURE RELEASE" (QG engine models WITHOUT EURO-OBD), EC-1001, "FUEL PRESSURE RELEASE" (QR engine models WITH EURO-OBD), EC1443, "FUEL PRESSURE RELEASE" (QR engine models WITHOUT EURO-OBD).
– c) Disconnect battery ground cable.
●Always replace O-ring and clamps with new ones.
●Do not tighten hose clamps excessively to avoid damaging hoses.
●Do not kink or twist tubes when they are being installed.
●Do not tighten hose clamps excessively to avoid damaging hoses. Tighten high-pressure rubber hose clamp so that clamp
end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber hose clamps.
Ensure that screw does not contact adjacent parts.
●After installing tubes, run engine and check for fuel leaks at connections.
●Use only a Genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the MI may come on.
●For servicing “Evaporative Emission System” parts, refer to
EC-554, "EVAPORATIVE EMISSION SYSTEM" (QG engine |
MMA104A |
|
models WITH EURO-OBD), EC-952, "EVAPORATIVE EMIS-
SION SYSTEM" (QG engine models WITHOUT EURO-OBD), EC-1408, "EVAPORATIVE EMISSION SYSTEM" (QR engine models WITH EURO-OBD), EC-1723, "EVAPORATIVE EMISSION SYSTEM" (QR engine models WITHOUT EURO-OBD).

1.Remove air duct and upper air cleaner case.
2.Remove fuel filter protector.
3.Disconnect fuel hoses from fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4.Remove fuel filter with bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed, immediately wipe it off.
PBIC0739E
5.Using band-type filter wrench (commercial service tool), remove fuel filter.
6.Turn fuel filter upside down to drain fuel.
7.Remove drain plug from fuel filter.
SBIA0136E
INSTALLATION
Install in reverse order of removal, paying attention to following.
●Replace O-ring on drain plug with new one.
●Screw the fuel filter by hand until O-ring contacts sealing surface of bracket. Then tighten it by turning approximately 2/3 turn.
●After installation, bleed air from fuel path. Refer to FL-5, "Air Bleeding" .
INSPECTION AFTER INSTALLATION
Run engine and check for fuel leakage at connections.

FUEL FILTER (YD22DDTI)
Air Bleeding
After fuel filter is replaced and after fuel system components are removed/installed, bleed air from fuel path as follows.
1.Move priming pump up and down to bleed air from fuel path.
2.When air is bled, pumping of priming pump becomes heavy stop operation at that time.
3.Crank the engine until it starts. Do not crank the engine for more than 30 seconds.
4.If the engine does not starts, stop cranking and repeat step 1 above.
5.If the engine does not operate smoothly after it has started, race it two or three times.
EBS00GX7
PBIC0740E
6.If air cannot be bled easily (pumping of priming pump does not become heavy), disconnect feed-side of
hose between fuel filter and electronically controlled fuel injection pump. After that, operate priming pump and confirm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine mount insulator.
