yes anywhere there is vac is suspect to a vac leak. ck your fuel trim with a scanner and that will confirm if there are no other vac leaks

The gasket under the fuel rail is called the intake manifold gaskets (O-rings). It's very common to have a vacuum leak there. Replace those O-rings and upper plenium also. the most likely complaint is, runs bad cold and once it warms up to operating engine temp it seems to run better.

Just replace the intake manifold and upper plenium o-rings. You are over thinking the problem. You have techs that have years of experience giving you the fix.
