O ring size on 6.9/7.3 injectors.

[CrippledEagle]

I just recently put a return kit on my 6.9. About a month afterwards I blew a head gasket. I picked up a 7.3 IDI to replace the 6.9. Of course I want to transfer the new return caps and lines. What o rings do I ask for at the parts stores for the injectors? I really don’t want to buy an entire new return set just to get the o rings.
Thanks in advance!

There's some vendors that will sell you just the O-rings. Give Russ (Typ4 on here) a PM> I'd say try Wes too, but he's not shipping anything currently. You might also try Mel (Agnem on here) at Conestoga Diesel. These will be the better quality viton O-rings too. They last longer than the regular rubber ones.

McMaster Carr has them also, bags of a 100 pretty cheap

"-111" or "dash 111" is the size, 7/16id-5/8od if I recall correctly.

I remember something in the part number that was "111" as well. Although in my case I ordered Viton rings.
