This should be clear if you look while someone else is cranking the starter.
A better way to do this is to short across the two exposed terminals on the
fuel pump relay with a small clip lead so the pump will run while you look.
DO THIS QUICKLY or you will spill a lot of gas and probably burn down the
barn and the car!
Once you find the leak, which will be obvious, you need to replace that
part, probably a hose or injector. You will want to replace ALL the fuel
lines that are at pressure (28-30 psi,) not just the easy to reach ones.
GOOD quality 5/16" hose works fine here.

If it is coming from the injector hose, you can carefully cut the hose off
the injector and replace it. If it is coming out elsewhere they must be
replaced.

Probably not a problem. You should worry more about the injector valves
themselves being rusted shut.

You're getting ahead of yourself. First you need to get it to idle, then to
run at speed, then to have the right amount of power. One thing at a time.

If you mean the fuel pressure regulator, then it is a spring loaded valve
that only lets fuel through when the pressure has reached 28-30 psi. I
don't know anyone who can blow that hard ;-) In the reverse direction it
takes MUCH more.
