2001 2500 4x4<br>BD guages. <br>They came with a fitting to hook up the boost to the eng.<br>But it doesn't tell me where or how ???<br>Guessing it goes in the intake someware, But I guess I'm just to stupid to figgure it out <br>At this point I could really use a picture :

 

There is a plug on the intake that you remove and replace with your new fitting. On the 12V, the fitting is just below and behind the airhorn.<br>The alternative is to drill and tap the air horn.<br>george

 

On the drivers side of the block there are two plugs directly behind the fuel filter housing. The one closest to the filter housing is the one to remove. You'll need a bushing to step down from 3/4 to your fittings that came with the gauge. <br>

 

Check out the bottom of this page to see how/where to install the boost line into the test port:
