A high-pressure pipe which has depressions
such as visible vertical slit scar (b), patchy scars
(c) etc. on the taper seal section of its connector
((a) part: within 2 mm from the tip), or a high-
pressure pipe whose (d) part (end of the taper

finger nail due to fatigue, may cause fuel leak-
age. In these cases, replace the high-pressure
pipe.
