NOTE: A fuel tank is comprised of 3 components:
the tank, the fuel pick-up neck and the filler neck.
The necks are injection molded and the tank is
then blow molded over the necks. During the
molding process, a small molding seam may ap-
pear on the inner side of the necks at approximate-
ly 4 mm (5/32 in) from the base of the neck. It is
a normal situation to have a molding seam and it
should not be confused with a crack.
