Upon replacing my injectors somehow I managed to scatter all the parts on one of my wiring harnesses I managed to find the blue rubber piece but can't find the orange piece (looks like the one in pic) what is the purpose of these and how screwed am I?

 

Holds the contact prongs in position and helps them keep their tension. Might work for a while without it, or might go intermittent pretty quickly. I'd cut one at the scrapyard and splice it in if you can't find the part.

 

Alright well one of my fuel rail ports got destroyed so I got a few days now
