Periodic Maintenance Procedures
Fuel Hose Inspection (fuel leak, damage,
installation condition)

The fuel hose is designed to be used throughout the vehi-
cle’s life without any maintenance. However, if the vehicle
is not properly handled, the high pressure i nside the fuel
line can cause fuel to leak [A] or the hose to burst. Re-
move the fuel tank (see Fuel Tank Removal in the Fuel
System (DFI) chapter) and check the fuel hose.
Replace the fuel hose if any fraying, cracks [B] or bulges
[C] are noticed.
•
Check that the hoses are routed according to Cable, Wire,
and Hose Routing s ection in the Appendix chapter.
Replace the hose if it has been sharply bent or kinked.
