Case 530 CAV style injector

[Kcavery2019]

I have a 1965 case 530 CK. I believe a 188d engine. Serial #8255207 and model# D530TC.
Apologies as I am new here and still learning. I have concluded these are CAV style injectors that were later replaced with pencil style injectors. I just bought this non-running tractor and finished rebuilding the fuel pump and it seems the return line is missing a nut and needs new seals. The nut may be replaceable at any hardware store (haven’t checked yet) but I am having trouble identifying the injectors and finding the return line seal. They seem to be a rubber or plastic that threads up into the nut and seals around the return line. Anyone know where to look or have any model#s for these injectors? Appreciate any help. Happy tractoring

Your local CIH dealer will have the sleeves and the nuts should be still available. I have a note at the shop with the part numbers for them in 1/4", 5/16", and 3/8" sizes IF I can find it, but a good counterman should be able to find them without even looking them up. (Wonder if yours may be 3/16", but they should be available, as well.)

Or, check with a nearby fuel injection equipment service shop, they will have the sleeves, for sure, and perhaps the nuts.

A CIH dealer or a fuel injection equipment shop, got it. I’ll start looking around and see what I can find. And it seems the correct terminology is a “sleeve”. Thanks a ton

The rubber compression brass nut should be available at the NAPA store. I have the rubber line grommets in 3/16, 1/4, 5/16, and 3/8 inch line sizes. I just repaired a 630 pump and CAV injector set for the early 188 head, injector tips should still be available if needed.

Rich, I have several of those core injectors if needed.

In a pinch, one can use good vacuum or un-reinforced fuel line in the right size. Real ones are cheap enough. Go wild, get the whole set! The nut is specific to that fitting tho.
