Dead Head Injector Rail?

So I'm reading up about WVO systems on the 7.3L and I find this on the frybrid.com website. Is there any truth to this stuff and is there any mods for it?

"While the 1999-2003 Ford Powerstroke Diesel (PSD) was an award winning design, it had issues. Most noteworthy was Fords attempt to lower fuel tank emissions by preventing fuel which had been heated in the fuel rails from being returned to the fuel tank. This was accomplished by dead-heading the fuel in each head (fuel is fed into the fuel rail in the head, from which each injector gets its fuel, this "rail" however has no outlet).

This solution created several new problems; it caused the injectors fartherst away from the fuel inlets to be starved for fuel making them inefficient and noisy, it also allows the fuel in the fuel rail to be heated - since it is no longer flowing - causing additional injector noise and wear. In an attempt to correct the fuel starvation issue, Ford replaced the #8 injector on some engines with a different injector called the "Long Lead Injector" rather than the standard "AD" injector. The problem persisted and Ford elected to go ahead with production of the motor while continuing work on the replacement motor, the 6.0 PSD introduced in 2004.

These problems can cause poor mileage, loss of power, and noisy operation. Some of the effected trucks also exhibit a noticeable knock at idle. The audible knock that occurs under acceleration between 1500 and 2000 rpm. Engines that are knocking usually are also experiencing low power through the 1500-2000 band, poor fuel economy, and may or may not also have a knock at idle. This is because of air being drawn into the fuel system and trapped there. We repair this by adding an adjustable fuel return from the fuel rails in the cylinder heads back to the tank. The air can then be evacuated from the fuel system."

Yes, that is correct. That's why alot of people make regulated return setups for their trucks
