There is a very large and fat o-ring that sits on top of the injector to act like a compression spring under the injector bracket.
There are four tiny o-rings on the fuel hose fittings.
And there are some internal o-rings behind the injector tip, inside the injector body.
The entire injector tip seals metal to metal against the cylinder head. No o-ring involved in sealing the injector to the cylinder head.
Note: Ficht fuel injectors are entirely different from automotive injectors. Do not fire the injectors unless they are bolted into the cylinder heads. See my signature links for mre Ficht info.

All the injectors are metal to metal. The only o-ring is in the top bracket.
K447 shows the oring in the top bracket in this post:
The o rings are pretty cheap. Just need to make sure the mating surfaces are extremely clean and smooth.
Edit** took too long to respond and he already answered your question!! haha
