Abstract
A fuel injector includes a barrel having an insert recess therein within which an insert is disposed. A facing surface of the insert is located opposite a base surface of the recess and forms a passage interconnecting a high pressure fuel passage and a valve bore. High pressure intersecting bores are thus avoided, leading to a reduction in structural failures.
