the FRx connects to opposite fuel ports to the oem fuel line. It cures the "deadhead" system. The benefits are it relieves the air introduced into the fuel and not thru the #8 injector, that whats goin on now. It'll smooth out the idle, and somewhat "cure" the cackle that the motor has. Another idea when doing the FRx is to do the HUTCH mod.

For a stock or near stock fuel system and injectors it is a good idea IMHO. But if your going to do that you might as well do the pre-pump mods too.
