When replacing fuellineparts, besure toobserve thefollowing:
• Put a"CAUTION: INFLAMMABLE" signinworkshop.
• Donot smoke whileservicing fuelsystem. Keepopenflames andsparks awayfromwork area.
• Besure todisconnect batterygroundcablebefore conducting operations.
• Besure tofurnish workshop withaCO

fireextinguisher.
• Put drained fuelinan explosion-proof containerandputlidon securely.
CAUTION:
• For ECCS engine models, releasefuelpressure fromfuelline. Refer toEC section ("FuelPressure
Release", "BASICSERVICE PROCEDURE").
• Donot disconnect anyfuel lineunless absolutely necessary.
• Plug hose andpipe openings toprevent entryofdust ordirt.
• Always replace O-ringandclamps withnewones.
• Donot kink ortwist hose andtube when theyareinstalled.
• Donot tighten hoseclamps excessively toavoid damaging hoses. •
• When installing fuelcheck valve, becareful ofits designated direction.RefertoEC section ("FUEL
CHECK VALVE", "EVAPORATIVE EMISSIONSYSTEM").
• After installation, runengine andcheck forfuel leaks atconnections.
