No. There are indeed 2 O-rings, the slim one is ~1x10mm and a thick one is ~4x12mm (don't
quote me on sizes).
They hold injectors in the nest, air tight. If 1 or some of them are loose, you'll get all
the classic syndroms of a vacuum leak (rough idle etc.).
If you decide to replace them, _make_sure they are OEM! My buddie had replaced them with
the matching ones, made out of a regular rubber. A month later gasoline vapors turned them
into a gummy mess, which was a royal PITA to fix.
What you need is a set of *Viton Tipped Injectors*. It's the injector itself, that leaks
fuel and loses pressure, coz the _internal_ rubber o-rings failed.
