There won't be any problem due to air in the capillary tube. The air (if
any) will compress when the oil pressurizes it, but it will be at the same
pressure - the only indication of air in the line might be residual
pressure after shutdown (but I doubt it)
If you really feel paranoid, bleed the fitting- put the gauge on lightly
(just until the fitting is snug), start the engine, loosen the fitting
until oil gooshes out and gets all over the carpet, do it up, shut off
engine, tighten fitting. Personally, I'd take my chances with air-in-the
lines.
As the oil PSI is only really indicative of "broken oil pump", "no oil",
or "worn out engine", the accuracy is not paramount.
