my dad has an 04 5.9 that i have a boost gauge for i am not familiar with the crs & was wondering which hose do i cut for the t pipe for gauge i let friend put it on & he put it in what me & autozone guys both think is the heater line

 

Holy crap, dude. Punctuation is a good thing...

 

Heater line hmmm can you take a pic?

 

Oh wow... As far as I know there is no boost ref line anywhere under the hood. 12v is a different story, anyways your easiest way to do it is buy a "boost bolt" it takes place of one of your intake bolts. Connect the line to it and your done. Curious, what does the gauge read as it is now?

 

22max 10 regualer driving & it had 6.5 when idling the idle was what made me check behind him.i could send ya a picture message over phone i cant seem to upload pictures for some reason

 

Ahhh yea something is wrong... I'll pm you my number cause I wanna see what you have goin on.

 

the boost bolt works very well but it has been known to cause a flutter with some gauges but, with the bolt no drilling or taping is required
