Can you hear the fuel pump run?

If you're concerned that it might be flooded, just unplug the fuel pump relay 
under the dash, to the left of the steering column on the firewall. That keeps 
the pump from running.

Not a pressure regulator; it's a pressure sensor.

That's the right part. The riveted one is a replacement part, just newer than 
the car. You can insert it either way; it doesn't matter. It's a transformer, 
inner terminals are one winding, outer terminals are the second winding. 
Reversing the plug just reverses BOTH windings for no net change. Clever, Yes?

The resistance readings you got are fine.
