Precaution for Fuel
(Unleaded Premium Gasoline Recommended)".
 Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosion-proof containe r and put the lid on securely. Keep the container in
safe area.
- Release fuel pressure from th e fuel lines. Refer to EC-87, "
Fuel Pressure Check" (VQ35DE) or EC-
665, "Fuel Pressure Check" (VK45DE).
- Disconnect negative battery terminal.
 Always replace O-ring and clamps with new ones.
 Do not kink or twist tubes when they are being installed.
 Do not tighten hose clamps excessi vely to avoid damaging hoses.
 After connecting fuel tube qu ick connectors, make sure quick
connectors are secure.
Ensure that connector and resin tube do not contact any adja-
cent parts.
 After installing tubes, make su re there is no fuel leakage at
connections in the following steps.
- Apply fuel pressure to fuel li nes with turning ignition switch
“ON” (with engine stopped). Th en check for fuel leaks at con-
nections.
- Start engine and rev it up and check for fuel leaks at connec- tions.
 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 Emi ssion System” parts, refer to
EC-40, "
Description" (VQ35DE) or EC-618, "Description"
