1. A fitting connection assembly for use in a fluid delivery system, comprising:
a first body, the first body including
a bore that is coaxial with a first axis, and
a retainer opening that extends coaxially with a second axis, the second axis being perpendicular to the first axis and offset relative to the first axis;
a second body, the second body including
an insertion portion that is disposed in the bore,
a fluid passage that extends through the insertion portion and communicates with the bore, and
an outer surface having a channel; and
a retaining pin that retains the insertion portion within the bore, the retaining pin including
a pin first end,
a pin second end that is opposite the pin first end, and
a pin longitudinal axis that extends through the pin first and second ends,
wherein
the retaining pin is disposed inn the retainer opening such that a portion of the retaining pin resides in the channel,
the retaining pin is elastically expandable and contractible in a direction perpendicular to the pin longitudinal axis,
the first body is a fuel rail,
the second body is an inlet fitting of the fuel rail, and
the channel is linear.
