I'm working on an install right now and I have a few questions.

Fuel EVAP System:

I have been doing some browsing and it looks like when your running an AEM EMS none of the EVAP system is controlled anymore. I took a picture of this area last night:

Am I correcting in assuming that I can remove the plumbing and components that I have circled? It looks like you're able to remove the entire system up to the fuel tank and then cap those lines. The only thing I'd like to avoid is excess pressure in the fuel tank, but I haven't found a solid way to deal with that problem. Is it really going to be as simple as finding and fitting a venting fuel cap? What are the best (safest) way(s) to block and cap off the lines for this system?

Stray Coolant Line:

I have the following line as seen here:

I believe this is the line that flows coolant through the OEM throttle and intake manifold. I'm under the impression that at this point this line is no longer necessary. What is the best approach in capping off this line?

I appreciate peoples thoughts and opinions. If there is a different section that would be more appropriate for these questions please forward me in the right direction. I've been trying to do some digging on my own but I can't seem to come up with anything solid.

I could be mistaken, but I thought with the new AEM V2, it does control EVAP.

I know the older ones don't. You might have a better chance of finding the answer in the FI forum. I know a lot of guys have done this sort of thing over there.

I've done extensive research on the subject of actually removing the parts (though I don't know about aem controlling it or not).

1) Best way is to take the lines that go from the gas tank to the evap (there are two) and put breathers on them like here

2) Capping the coolant lines, I put a screw in it that fit tightly, then put a rubber cap on it and zip-tied. Been going strong for 2 years with no leaks, though I'll probably change out the rubber caps soon as they're starting to dry-rot a bit. I constantly checked them the first year for any signs of fluid loss or malfunction and nothing.

These are the caps I bought. Random sizes to make sure you get a snug fit. http://www.autozone.com/autozone/acc...er=720714_0_0_

You can control the evap system with either the v1 or v2. You can take all that mess out including the stuff under the tank, just make sure the tank has a vent so you dont get a build up of pressure in the tank

Do you mean 'can't'?

If I pull the entire system out, and cap the lines going into the tank does it make sense for me to be able to use a pressure vented gas cap? Is that even a thing? I've seen some discussion on the forums about mounting a 1 way valve somewhere which I guess is an option as well. If I can do that entire process by finding a gas cap that would serve that purpose and just cap everything else off that is what I would like to do.

Also, if I just put breathers on the lines for the gas tank will my car perpetually smell like gas? That's really what I'm trying to avoid.

The last question that I have, is if the AEM V2 can actually control the system, do I need a vacuum line on it? If so is it safe to route that through my vacuum block? It doesn't seem like a great idea to run fuel vapor through the res of the vacuum system.

Oh Excellent. Thank you for that.

Now I just need to figure out what to do with that line. I have an extra line on the vacuum block, do I run it to the EVAP system? I don't know if it's ok to add that line to the vacuum block because as far as I understand it the air coming from that system should have fuel vapors in it.
