Checking Fuel LinesBBS005AE
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 PrecautionsBBS005AF
WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in the 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 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-6, "Precautions for Fuel" .
Before removing fuel line parts, perform the following procedures:
–Release fuel pressure from the fuel lines. Refer to EC-49, "FUEL PRESSURE RELEASE"
(QR20DE), or EC-392, "FUEL PRESSURE RELEASE" (VQ23DE and VQ35DE).
–Disconnect the battery cable from negative terminal.
Always replace clamps with new ones.
Do not kink or twist tubes when they are being installed.
Perform work on level place.
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 with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.
–Start engine and rev it up and check for fuel leaks at con-
nections.
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-27, "
EVAPORATIVE EMISSION SYSTEM" (QR20DE), or
EC-366, "
EVAPORATIVE EMISSION SYSTEM" (VQ23DE
and VQ35DE).
