FUEL RAIL MOD

[2whlfreak]

There is supposed to be a mod that opens the fuel rails letting fuel return back to the tank instead of staying in the head untill used. This is supposed to yield a 70HP increase. Anyone know what Im talking about or am I misinformed.

You can get a regulated fuel system from ITP or Diesel innovations which will give you a return back to the tank ... Not sure it will give you 70 HP though...

It would be a regulated return system. No HP increase like that. In fact my butt-o-meter felt no difference in power. Idles quieter and smoother.

Yeah, Regulated return is more of a supporting thing than to give you actual power.

at what piont would thise almost be required to suport. and would the hutch mods (intank & prepump) produce the same results since there would be no air and just steady flow?

[Lord Tauk]

You could probably start to benefit from it, all trucks probably can especially with the cackle issue.
