Checking and replacing the fuel lines

Carry out the inspection while the engine is cold.

Open the engine hood (page 74).

Check all fuel lines and hoses at the engine, fuel reservoir and fuel filter for condition (cracks, bulges, hard
spots) and firm seating of the connections. If necessary, have the lines and hoses replaced by trained per-
sonnel.

Close the engine hood.
