what are they and how much do they help

 

could you explain what these are and what they do

 

that is what i am asking i havent heard of them befor

 

niether have i, who did you hear about them from

 

a cupple guys from woodruff diesel have. them and they sell them, thet got them on some big time pullin trucks

 

what do they connect

 

i think the lines 2 eather the pump or the injectors

 

They are between your injector lines and your injector. They are in the head.

 

thanks do they help much

 

ive heard they hurt idle and cause some leakage! I have no personal exp. ! Maybe someone will jump in here!

 

They will sure make your truck idle rough. They let more fuel through. Don’t think there worth the money.

 

Just run the stock ones. they only help with HUGE injectors.

 

alright thanks for the help

 

hailsley machine has some on there website for 150 bucks. Looks like they just took a drill and drilled them out to me, But i'm sure there's a little lmore to it

 

I have 200hp sticks and I don't nedd them. They are for a large amount of fuel. If you are running mild injectors, I don't think they will help. Your pop off pressure is still the same so it wouldn't let anymore fuel through a mild injector.
