Abstract: A connector assembly for connecting a fuel rail and an inlet tube having an inlet tube end and a raised annular flange a predetermined distance from its end includes a connector body and an annular clip. The connector body is attached to the fuel rail and includes an outwardly extending shoulder. The annular clip has a periphery with a generally U-shaped cross section including an inner leg and outer leg. The inner leg is inclined inwardly for engaging the inlet tube annular flange and the outer leg includes a resilient locking portion biased inwardly for withdrawal restraining engagement with the connector body outwardly extending shoulder. The annular clip is mountable on the inlet tube beyond the raised annular flange. The inlet tube is telescopingly received in the connector body and axially engaged as the locking portion of the annular clip is urged into engagement with the connector body outwardly extending shoulder.

Abstract: A fuel rail and injector assembly include a fuel delivery rail having an injector cup and a fuel injector having a mounting end mountable in the injector cup. The injector cup includes a receiving section having a necked down portion and a retaining portion, integral with the injector cup. The fuel injector mounting end includes an integral engaging section urgeable through the necked down portion and receivable in the retaining portion for snap fastening together the fuel injector and the fuel rail injector cup.
