Never smoke while servicing fuel system, use gasoline required by the regulations for octane number, before removing fuel line parts, perform out following procedures, - Put drained fuel in an explosion-proof container and put the lid on securely.
- Release fuel pressure from the fuel lines, - Disconnect the battery cable negative terminal, always replace O-ring and clamps with new ones, never bend or twist tubes when they being installed.
Never tighten hose clamps excessively avoid damaging hoses, after installing tubes, check that there is no fuel leakage at connections following steps, - Apply fuel pressure to fuel lines with turning ignition switch ON” (with engine stopped), - Start engine and rev it up and check for fuel leakage connections.
Use only a genuine NISSAN fuel filler cap as a replacement, for servicing Evaporative Emission System” parts, the actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here, inspect fuel lines, fuel filler cap and, fuel tank for improper attachment, leakage, cracks, damage, loose connections, chafing deterioration.
If necessary, repair replace damaged parts, after connecting fuel tube quick connectors, check that quick connectors secure, ensure that connector and resin tube never contact any adjacent parts, fUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY.
