What do you guys use?
I know guys like Ed sell the version that allows you to replace the nozzle, but does it work to as well upside down if you want to replace the top o ring?
I can only find info on the version that shows the injector upside down in the fixture.
I think I would find more use for a fixture that holds it right side up for getting that c clip out.
Sick of using shop towels to keep the body from getting marred from the vise jaws, or possibly worse. I don't like putting too much force on the body, and find myself doing more of these as the kid picks up more side jobs.
I know many have done it, but I don't like it
I don't have a tool to recommend but you can replace the top O-ring without removing the retaining clip. In many cases I wouldn't even remove the injector if it is just a bad top oring.
Pretty sure there is a youtube video on it.
You could pick up some high-strength UHMW sheet or bar. If sheet, it cuts easily into two bars. Clamp lengthwise, bore a hole centering at the seam that would fit the body of the injector. Heck, you could do that with plywood too, might just need to laminate sheets to build up the thickness. Or soft pine. You're not holding for high torque. In a vice, or get creative using it with with screws, bolts, clamps ......

I've done it that way as well Pete, it's not a horrible way to do it if you can catch on. I'm looking for an option that works for both, just hard to tell by pics

Thought did cross my mind Jack, I have access to what is needed to do a mild steel version. Time to get the cutting oil out.
I remember ToolmakerRob was going to come up with something last year, not sure what he ended up doing.
I go back towards plastic or wood as my metalworking tools are limited while woodworking are not, especially if its just holding something to not move around. I've got a fair about of leftover UHMW on my shelves from projects, it stiff and strong, and very not-marring. With its high density approaches Teflon. We used it a lot in my carbon fiber days, so I fall back to mama.
My thinking was along these lines, but you could even use these and bolt to metal or wood held by a vice so the injector is vertical.
I like the UHMW idea Jack.
I use it here at work, it does not lend itself to things bacterial in nature, something we need to keep the USDA(and our animals) happy during inspections.
I have some pretty thick stuff to choose from, I might go that route for starters.
I just use a deep socket to set the injector in and then place that in the vise.
You could even get a cheap one and grind down the outside so you have some flat spots for the jaws.

I cut a piece a bit thicker than 1/2", drilled and cut in the middle. I think it needs to hold about 80 ft lbs. When I didn't clamp it down enough, it would rotate when I took the injectors apart.
When replacing the top oring, I just hold it by hand and did not try to replace the retainer c-clip. That's just too hard for me. I got 1 out before, but it's just too hard for me and not even needed to replace the o-ring.
I used my spare engine to change out top orings. Maybe pick up a cracked head and use that to hold the injector. Kind of a one use tool/fixture but doesn't every engine have a one use tool of some sort.
