The stock Bosch injectors have the groove at the top that the injector clip slides into and keeps the injector in the fuel rail. Do the Delphi injectors have this groove also? If not does it just stay in the rail because the o-ring is tight enough and the rail keeps it from going anywhere?

I used Bosch #52 before, without clips. No problems.

i don't use clips with my delphis, works just fine. just make sure you bolt the rail down properly. sometimes those threads get damaged, i had to perma coil one of mine.

I think clips help in high fuel rail pressures...my Bosch #52's had grooves.thanks vitesse...the rubber o rings/gaskets get pressed down against the clips expanding and forming a better seal

I did not manage to get the clips on my #65 Delphi's and left them out. Has been no problem for the last six months.
