Bleed Fuel Injection?
I've never heard of the need to do that because one end of the system is open anyhow, and it bleeds itself. But, yoiu could find the fuel feed line and disconnect it from the fuel rail, then set the Ignition to ON until fuel comes out. There is also a schrader valve (looks sorta like the valve for putting air in the tires) that you could open, then set the ignition to ON until fuel comes out.
But, if you recently replaced a fuel pump or filter and want to get the gas to come up, all you need do is the normal stuff to start the car -- I assume the motor is actually in a truck, but that's not important.
You need to bleed a closed system, like brakes or a hydraulic clutch. The reason is that the air that is trapped in the closed system will adversely affect the operation of the system. The fuel system is not closed, per se, because the injectors open and let the air out. By definition, it self-bleeds.

Is the 7.3L not a Diesel engine? Whether and how to bleed (purge air from) the fuel system will depend on exactly which of these you may have. It is not the same animal as the big gas burner. If it is a Diesel, and you have replaced the fuel filter, you should have filled the new filter with fuel before installing. From there, any bleeding or purging required may differ in process. There are several very knowledgeable posters here and an very good Ford Diesel forum on the web. Sorry, I don't immediately have the URL for that.
