Call Todd at TC diesel and he will set you up. He mods the inlets and outlets as well as ports the rail
Its very easy to do.. Just was curious if anyones done it on a cummins..
TC diesel does lots of them....his modded rails come with the fittings ported out along with alot more :thumbsup:
Be worth a shot if you got one spare laying around. I'd rather leave it someone like T&C or Wicked.
I don't see any reason to port the rail or to go to larger connector tubes. It makes sense in theory but I have not seen anyone notice any real world gains. Trucks are running 750-1000hp with stock tubes and rails so I don't see the need. JMO.

Heck my 750 was with a cat and going thru the factory fuel filter, which are parts most people say are a must to remove to make power. But what do I know.

You pushed a cat through your fuel filter? That's one hell of a lift pump! jk! I had Todd do my rail just to increase volume. I don't have any before and after dyno comparisons to show any difference and can't tell a difference from my SOP dyno.
When you say "rail fitting" are you talking about the outlet fitting at the cp3 or are you talking the actual welded fittings onto the rail?

The modded outlet fitting is available in any bag of parts typically.

the ported outlet fittings welded to the rail are only available on modded rails from wicket or TC as mentioned above.
U dont gain alot power its more volume and alot of other benefits that tod can explain he built my whole system from pumps to rail tubes
