Ragers, probably cause you aren't understanding the function of the fuelling system, and will potentially do harm to it.

The point of the return line is to keep having fuel flowing, always a fresh supply in the rail for the injectors to feed from.

Part of the recircuation system is to cool the fuel pump. Secondly, the constantly flow of the fuel makes it easy on the fuel pump, otherwise you created a dead end in the system, and the pressure will cause excess stress and heat in your fuelling system, more likely causing premature failing of your fuel pump.

Not sure if it would affect injector performance or not, hard to say.
