There are 2 fuel lines connecting to the fuel injector rail. The larger line is the pressure line and the smaller line is the return line. The smaller line attaches to the fuel pressure regulator. You will notice that the regulator also has a vacuum line attached to it. If you are planning on changing it your self, let me know. There is a specific way to change it for safety reasons.
Let me know.

The motor more than likely won't start or it could flood out with gas.
Fuel pressure regulator controls fuel pressure. You should have 30psi at the fuel rail for the motor to start.

I'd check the manual transfer valve on the dash. They have a tendency to go bad after awhile. Cause 1000 different symptoms, and be the last thing checked/replaced. It's probably the cheapest place to start. The pump under the driver's feet is usually the last one to go in my experience, but the secondary culprit is normally the main pump in the rear tank.
Next time it tries to stall, toggle the fuel switch and see what happens. Same with a hard start. Back and forth a few times quickly.
Hope this helps.

low fuel pressure can be caused by fuel pump or pressure regulator. The regulator is on the upper side of the engine and looks like picture below. Check the vacuum hose all the way to see if it has a loose or broken connection. The regulator is much easier to replace that the pump, so I always recommend one replace the regulator before the pump. If you know someone that can check the fuel pressure before the regulator, you can actually determine which part is bad.
