Claim:
1. A fuel injector retention arrangement for retaining a fuel injector to a fuel rail socket of a fuel rail, said fuel injector having a fuel injector upper housing which defines a fuel inlet to said fuel injector, said fuel rail socket having a fuel rail socket body, and said fuel rail having a fuel rail volume which receives pressurized fuel; said fuel injector retention arrangement comprising: a fuel rail socket interior space defined within said fuel rail socket body such that said fuel rail socket interior space extends into said fuel rail socket body along a fuel rail socket axis, said fuel rail socket interior space being in fluid communication with said fuel rail volume; a fuel injector retention groove defined on said fuel injector upper housing such that said fuel injector retention groove is disposed within said fuel rail socket interior space and such that said fuel inlet is in fluid communication with said fuel rail socket interior space; a first retention bore defined in said fuel rail socket body and extending into said fuel rail socket interior space such that said first retention bore extends along a first retention bore axis that is substantially perpendicular to said fuel rail socket axis such that said first retention bore axis is laterally offset from said fuel rail socket axis; a second retention bore defined in said fuel rail socket body and extending into said fuel rail socket interior space such that said second retention bore extends along a second retention bore axis that is substantially perpendicular to said fuel rail socket axis such that said second retention bore axis is laterally offset from said fuel rail socket axis; a first retention pin disposed within said first retention bore such that said first retention pin extends through said fuel injector retention groove; a second retention pin disposed within said second retention bore such that said second retention pin extends through said fuel injector retention groove; and a retention pin retaining member which retains said first retention pin in said first retention bore and also retains said second retention pin in said second retention bore; whereby said first retention pin within said first retention bore extending through said fuel injector retention groove and said second retention pin within said second retention bore extending through said fuel injector retention groove retain said fuel injector to said fuel rail socket.
