ABSTRACT:
An eccentric member for coupling a fuel injector to an internal combustion engine cylinder head. The apparatus includes eccentric members that are rotatable to align fuel coupling components to compensate for gross accumulated component dimension tolerances, thereby allowing the use of economical and reliable O-rings to compensate for remaining tolerances. Embodiments of the apparatus include an eccentric, a coupling member and adapters having off-center fuel passages.
