I would think that with the vise grips in place you would be effectively raising the fuel pressure at the rail

If it were mine I would be wondering what the pressure at the rail was; both with the clamp in place and with it off.

If you are near a pick and pull or have a parts car available you can make your own fuel pressure gauge with the fuel rail connector and a trip to the hardware store.

In your image I have circled the piece you need from the fuel rail; cut a couple of inches back on the hose side and enough of the solid line to get a nice straight portion to make the compression connection on.

The next image shows the way it all goes together and what you need:

Then you simply disconnect that attachment to the fuel rail and make the connections to your test gauge. This is for testing purposes only. It would be a good idea to work outside and have a fire extinguisher at the ready. Once you start the car the gauge will read the pressure at the rail

I would hate to suggest that you replace the main fuel pump without having some pressure readings to think about.
