Abstract
A circular cross-sectional fuel pipe can be prevented from undesired rotation in an engine cylinder head, by a key-key slot combination having a relatively small radial dimension. The key slot is formed by a groove formed in a cylindrical sleeve that is press fit in a counterbore machined in the cylinder head. The mating key can be a ball, or pin, or bar press fit into a side surface of the fuel pipe.
