How much fuel pressure should a 7.3 have?

To optimize performance the fuel pressure should be relatively steady and 60-65 psi. If the pressure is in the normal operating range of 45-65 psi, but below the optimum small shims can be used in the cup of the piston and spring to increase the fuel pressure to the desired level.

How does power stroke work?

Diesel fuel is sprayed into the cylinder by the injector and immediately ignites because of the heat and pressure inside the cylinder. This is the same process described in How Diesel Engines Work. The pressure created by the combustion of the fuel drives the piston downward. This is the power stroke.
