Does anyone have instructions on how to drill out the injector connector tubes on a 1999 cummins?

 

Why would you want to do this?

 

I would like to know the same thing.
Do you have a huge set of injectors to feed? Thats really the only reason to do something like that.

 

This wont do you any good. The supply holes inside the injectors will still be three times smaller than the supply tubes.

 

He wants to drill the edge filter out of the tubes, no reason to do this till you have huge injectors.

 

I very curious tell me how that will help huge injectors. the DDPs I have in my engine have a flow rating not a HP rating. so I suppose that would qualify as huge.

 

I think there was a 8hp difference when we did back to back dyno runs between stock tubes and modified tubes adding 8ho on A truck with a Silver Bullet and DDP 62 liter or what ever they call their custom bigger than 200hp sticks.
