Ok guys I pulled my heads to replace my head gaskets and the line that runs to the driver side and the one that runs toward the rear of the truck were cut off. I planned on deleting the emissions system anyways but I don't know where they ran to to make sure they were properly blocked off. The truck has headers so I'm guessing that why the one to the drivers side was cut but I'm clueless about the one running to the back of the truck.

Also concerning the evap system is the vacuum line on the back of the throttle body riser the only one I need to block off? Then just add a filter coming off the valve cover breather?

Any help would be appreciated. Thanks.

 

Those are the air injection lines. The long one would have ran down to the cat.

As far as EVAP goes, there is no reason to remove the EVAP components. It doesn't hurt the engine at all, and the only thing you'll accomplish by venting it to atmosphere is making your truck smell like gas every time you park it.

 

Oh ok. I'll keep it on there then. I'll just have to get some new hoses. The factory plastic oneS were so brittle the snapped as soon as I touched them.
