How to remove charcoal canister and not get CEL?

[JSG1901]

I know this is a terribly old thread, but I'm hoping somebody who was in this conversation back in the day may be able to shed a little light on my version of the same question. 2000 Boxster S race car. As were others in this thread, I'm also trying to get rid of as many of these EVAP parts as possible, but mine look a little different than those shown here, AND I don't see any mention of whether or not we need to keep the fuel vapor purge valve.

Here's my whole system:

Here is a close-up of the purge valve:

And here's a close-up of the charcoal canister:

The letters on colored backgrounds show the various hoses and wires and are the same on all the photos for easy reference.

Here's what I think I know...

1. A, B, and E all go down toward the gas tank.
2. B seems to go INTO the gas tank (I can hear bubbling if I use compressed air in it).
3. C seems to come from the purge valve to the charcoal canister.
4. D comes from the gas filler "cup" in the fender, and down into the purge valve.
5. E goes between the purge valve and...? Maybe the gas tank. I can't tell where it ends up, nor which way the flow may be.
6. F and G are electrical connections on the purge valve.

My questions:

1. Do I have to keep the purge valve, or can it be removed, too?
2. Either way, which of these parts do I need to keep (and/or connect to one another) and which can I remove?

I've tried blowing air down all these hoses and, so far at least, I haven't been able to hear anything at the back of the car...but I may need to have an assistant help me with that.

Any help you may be able to provide will be greatly appreciated. Thanks in advance!

Hey J, any progress with this project? This is coming up on my to do list and I was hoping you figured these out. I have no idea what goes where, but there should be at least one hose that runs from the evap canister back to the intake manifold and one that will vent to atmosphere somewhere near the rear. I have a feeling that the third line from the evap canister feeds back to the purge valve, which maybe serves to be a central "hub" for collecting fumes and feeding them to the evap canister. That last part is purely a guess though.

Hey guys, were you able to figure this out? I am looking to do the same on my 2000 S race car and have this exact same setup as shown in the pics with the labeled letters. Trying to figure out the best way to do this....
