A mounting arrangement includes a fuel injector, a fuel injector cup, and a fastener. The fuel injector includes a body that defines an interior fuel passage that extends between an inlet and an outlet. The body of the fuel injector also includes first and second exterior grooves. The first exterior groove receives a compliant seal, and the second exterior groove is located between the first groove and the outlet. The fuel injector cup includes an end that defines an aperture through which passes along an axis the inlet of the fuel injector. The fuel injector cup also includes inner and outer surfaces. The inner surface contiguously engages the compliant seal, and the outer surface includes a shoulder that faces generally opposite the end of the fuel injector cup. The fastener includes first and second portions. The first portion engages the second exterior groove on the body of the fuel injector, and the second portion engages the shoulder on the outer surface of the fuel injector cup so as to axially retain the fuel injector relative to the fuel injector cup. The first portion is axially spaced from the second portion such that a first axial measurement between the first portion of the fastener and the compliant seal exceeds a second axial measurement between the end of the fuel injector cup and the shoulder on the outer surface of the fuel injector cup. Details of the fastener and a method for using the mounting arrangement are also included.
