Abstract
A fuel injector isolator includes a support member which is rigid and which is annular in shape being centered about an axis such that the support member has a support member inner periphery which circumferentially surrounds the axis and includes a concave region. The fuel injector isolator also includes an isolation member which is resilient and compliant and which is annular in shape being centered about the axis such that the support member has an isolation member outer periphery and an isolation member inner periphery which accommodates the fuel injector therein. The isolation member is located within the support member inner periphery and includes 1) an isolation member outer periphery upper retention surface which engages the support member first end surface and 2) an isolation member outer periphery lower retention surface which extends into the concave region and engages the concave region of the support member.
