Increasing fuel pressure on a stock 7.3

My truck is basically stock and I'm rebuilding fuel bowl, is there any benefit changing out the spring to increase fuel pressure without any mods or tunes?

Is it blue spring I see people talking about?

idk i just used the BB under the spring. I even tried a pellet before. both worked and was basically free.

No, blue spring is 6.0.

Look into a fuel rail crossover.
