Can anyone tell me were I can get instructions on how to drill out my connector tubes on my 99 cummins Thank you!

 

Why are you drilling them out?

 

I want to drill the screens out to get more fuel flow

 

ive ran the bigger tubes with out the screens. not worth it IMO, and i was pushing 530 hp. Its your truck, do what ya want tho! good luck

 

Unless your running one of the new Monster VPs I doubt you will see any kind of gain other than a rough idle.

 

yea mine is only pushing 400 hp and i was going to change over to 150hp injectors and drill the tubes out but if it's not going to help i wont mess with it

 

I wouldn't bother with the screens, and I'm not convinced that bigger tubes do a whole lot to promote fuel flow - JMO!

 

One of my friends has an II HRVP with larger connector tubes. It sounds AWESOME at idle It lopes like a pullin truck or somethin. Not sure if the bigger connector tubes helped him out any but it sure does sound good

 

I have a set of .093s I took out last night. I put them in with my marine injectors and noticed no difference but when I put my 150s in it idled terrible. NO POWER DIFFERENCE
