No, it is not “normal”.
Don’t want to insult your intelligence , but here is how I see it;
If you saw air bubbles (independant where you saw then at), it means there was pressure in the rail.
Pressure in the rail should be “fuel only”.
Air bubbles = fuel leaks = fire/explosion.
Even if you ran it and it did not start on fire, you will have lean running cylinders and blow the HG or something else.
Get it fixed!

where at in the fuel rail are the bubbles coming from? at the fpr? at the injectors? at the fuel line hookup? is the rail itself cracked, bent, corroded?

From the valve on the fuel rail.

it's coming from inside the scrader valve where you hook up a hand held pressure gauge?
if so, try using a tire valve core tool to tighten the core back in. if that doesn't work, head to the junkyard with the valve core tool and get a handful of cores to try until you find one that doesn't leak.
