Checking Fuel LineINFOID:0000000001722976
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001722977
WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in the work area.
Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
CAUTION:
Use gasoline required by the regulations for octane number. Refer to GI-45, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines if necessary. Refer to EC-379, "
Inspection" (HR16DE with
Euro-OBD), EC-681, "
Inspection" (HR16DE without Euro-OBD), EC-1035, "Inspection" (MR18DE).
- Disconnect the battery ground cable.
Always replace O-rings and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Perform work on level surface.
Do not tighten hose clamps excessively to avoid damaging hoses.
After connecting fuel tube quick connectors, make sure quick connectors are secure.
Ensure that connector and resin tube do not contact any adjacent parts.
After installing tubes, make sure there is no fuel leakage at connections in the following steps.
- Apply fuel pressure to fuel lines by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube connections.
- Start engine and rev it up 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
MIL may come on.
For servicing “Evaporative Emission System” parts, refer to EC-379, "
Inspection" (HR16DE with
Euro-OBD), EC-683, "
Inspection" (HR16DE without Euro-OBD), EC-1037, "Inspection" (MR18DE).

Use hand tools, power tools (disassembly only) and recommended
special tools where specified for safe and efficient service repairs.
When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precaution for Three Way CatalystINFOID:0000000001606119
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
When checking for ignition spark or measuring engine compression, make tests quickly and only when nec-
essary.
Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the
catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precaution for Fuel (Unleaded Regular Gasoline Recommended)INFOID:0000000001606120
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.
