The white interior O ring on these injectors, does anyone know what size this is? ID, OD, Thickness, type of material? I've only seen those in a complete rebuild kit that includes other parts that I don't need, but they don't say any of the info I am curious about. I haven't opened up one yet, but my apprehension with this project is that I really feel I should take the tips and clean them in the US cleaner, but don't want to take off the shell if this white o-ring will have to be replaced if I don't have replacement parts. Anyone know the answer on this thread? Thank in advance. I'm starting my project today, and will hopefully finish by Thursday. (I have other things to do while I'm in here.) I have all the exterior ones. I've edited this post as I realized I linked the wrong photo... C'mon coffee!!!!

Sorry for the confusion, I have all of the O-rings for the exterior of the injector including the black and white and copper to which you're referring. What I'm talking about is the internal o ring and based on the picture there's only one. Those are not included in the kits. And the internal one is the one I'm wondering about. Thanks for your reply though.

The internal one is in the kit Ed sells.

I am fighting getting 5 & 7 injector cups clean. sides are all fine, it's just the very bottom outside edge that would be the buildup outside the copper gasket from the injector tip. I'm mean I've been at this for hours.... I have the Alliant brushes, and I'm using carb cleaner, wd-40, microfiber clothes.... I know it's just a thin buildup, and honestly it should be outside of the copper gasket. But does anyone have any tips to get these as shiny as the 1-4 ones? Honestly, I left 6&8 with just a micro bit, but it was far enough away from the copper I'm not worried about it, but 5&7 are a little more concerning... Unless it's clean enough by having the rubber oring seats clean, and the middle clean. ???
Also, I have T-40 hold downs, and everything I read says 24'lbs of torque, but a couple threads, with no supporting documentation say 26-27'lbs, and one thread said 31'... Now, maybe this is for people who don't clean out the hold down bolt holes, but I spray them out a half dozen times, including once with carb cleaner AND I clean off the bolts themselves AND blow out the hold down bracket, as there is usually oil in that as well. So, I'm not as concerned about hydro-torquing that some people may be over torquing to compensate... ??? Thanks

I missed that part, good catch. I hope my 27# is good. I’m still fighting the adjustable fuel pressure regulator. I’m sending it back and installing my blue spring.

In the end the torque spec is just maintaining the integrity of the seal between the injector, copper washer and cup so I went with 27 ft lbs feeling like more is probably better. We are splitting hairs between the lowest I have seen (24ft lbs) and the highest I have seen anyone talk about (32ft lbs). The difference between 26 and 27ft lbs seems marginal. A torque wrench could be off that much, even an expensive one. I used my digital Craftsman. I think making sure the cup is clean and threads are blown out make more of a difference than anything. The last thing you want is the hold down bolt to loosen up and allow the combustion chamber to get past the washer. I think that’s what was going on with those dark and dirty cups, there was some blow-by going on.

I ran across a post about injector torque specs and someone threw that tidbit of information in there. 32 is pretty high but the guy said he had always torqued his down that much. I’ll stick with 27.
