I pulled some injectors from a L59 flex fuel 5.3l from a 2006 Suburban. When I got home and was cleaning them, I realized they are a bit taller than my original injectors.
These are part number 12580426.
On the TOP of the injector, above the upper oring, most lifters have a little "metal shelf" or lip that I'm assuming is used to help keep the oring in place, however these do NOT have that metal lip, but instead have a really small groove, and a small plastic bit that snaps into it, that acts like the metal lip on others. I damaged the plastic ring on this set when changing the tiny filters.
I don't know the name of this ring to buy new ones.
Can someone PLEASE help me figure out the name of this little plastic ring?
