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 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.
