Default Vacuum line help

I am in the process of installing a p-51 intake and deleting my EGR. I removed all the vacuum lines attached with the EGR to the two main vacuum lines that come in near the fuel line. The diagram the fox lake gives is useless, cant see a damn thing and they arent returning emails or calls. Basically my question is where do I hook up the PCV and the vacuum line to the fuel pressure sensor? Can I just run a line from the stock vacuum line locations to each one of these? If so does it matter which one goes where?

Just run them to stock locations if you can to save yourself some headache. When you really think about it, all vacuum powered accessories work of the same amount of vacuum, some are just run to different size fittings for example the PCV.

Nope, as long as you aren't trying to run larger stuff like the PCV to a small fitting on the manifold or something like that, you'll be fine. You can really hook up pretty much any vacuum line to any vacuum source and be just fine.

man id just delete the pcv. i mean if you are deleting the egr then you arent worried about emissions so just go to autozone or somewhere and buy tow small breater filters for the valve covers. it will keep the engine cleaner anyway

I was thinking of doing that. Do I just plug the vacuum line under the intake then, it connects to the pcv and the factory vacuum line.

Yeah, if you are running breathers and deleting the egr, then just plug all the vacuum hookups that they used to go to. I have 2 k&n breathers that I'm trying to get rid of.....PM me if you are interested
