Abstract
A fuel system includes a fuel injector having an inlet conduit which extends along an inlet conduit axis and has an inlet conduit shoulder which is travers to the inlet conduit axis. A fuel distribution conduit supplies fuel to the fuel injector, extends along a fuel distribution conduit axis, and has external threads which threadably engage internal threads of a connection nut. A retention member is a segment of an annulus and includes a central passage extending axially therethrough and external threads which threadably engage the internal threads of the connection nut. The retention member is terminated in a direction circumferentially about the fuel distribution conduit axis by first and second end surfaces which together form a retention member slot therebetween sized to permit the inlet conduit to pass therethrough in a direction perpendicular to the fuel distribution conduit axis.
