The 6 o-rings that I replaced were the ones between the fuel injectors and the inlet manifold. There are another 6 o-rings between the fuel injectors and the fuel header that I did not replace.

I measured the old and new o-rings with a micrometer to see if they were the wrong size. The old o-rings had some ovality in cross-section, probably from compression, but seemed to be about the right size. Maybe they were old stock or the wrong elastomeric material.

The engine is the inline 6. It takes about 1 hour to change out the injectors - the only problem is a few bolts on the injector fuel header that are a challenge to get out.

I'm still getting a smooth idle, so I think this has fixed the rough idle problem.
