evap system just allows the fual tank to pressurise right? i.e when fuel goes out, air's gotta go in?

It let's controls the fumes by circulating it back to the intake/throttle body and lets pressure out of the tank.

Tht fuel and fuel pump make plenty of pressure, but when the pressure gets to high, it needs to be released. Supposedly the gas tanks fuel cap lets air in and out, but I would play it safe and not plug the fuel tank hose (EVAP to fule tank, once the EVAP is removed) and put that one way vaccume valve in. let's pressure out, but won't let air in.

here i thought the tank would actually be under negative pressure as the fuel was pumped out... interesting.

so a 1 way valve to let air out but not in, and that's all there is to it?

From my weeks of internet research, yes. lol.

basically the fumes of the fuel create the pressure and the fuel pump helps as well. Not sure of the science behind it, but they work hand in hand... makes sense I guess.

there are 2 ways to go about it, put the 1 way valve or plug the hose. I've read people doing both, some plugging the hose and claiming fuel cap lets air in and out and will last just fine and others saying that plugging it will cause too much pressure and weaken the gas tank quicker (not months) than if it was vented; hence why some people vent it. I've also read that some people just leave the hose as is and zip tie up some where open.

I prefer to start with the 1-way vent, it's a good middle area to start; if it doesn't work i can always plug it. worst than can happen with the 1-way vent is that there isn't enough pressure. If thats the case (which I'm sure it wont be) then i know leaving the hose open to flow both ways would not be good either, since the air pressure would be equal to the exterior, therefore no pressure in the tank.

I'm doing it to my car next week sometime; hopefully by Wed.

do a write on it when you do it and yes I can read
I just want to make sure I no what I'm removing..
also this doesnt throw any codes with the sensor being removed for the evap

talking about the sensor right by the alternator

I will do a write up, issue is I have a M3 now. So other than hose comparison, the vehicles placement of the EVAP could be different. But I'm pretty sure the basic idea the same; I don't think they would make each EVAP completely different (connection wise) for every vehicle. They all serve the same purpose, so hopefully it is for both our vehicles.

Is that a question?

Yes removing the EVAP system will throw codes.

ECU throwing codes for a system you've disabled?: RomRaider

What are the benifits of removing the EVAP?

just did a battery relocation: very easy. you can actually cut the standard tie-rods and then place the ends in a vice and bend them around to give them hooks. then just drill a pair of holes in the floor and voila, side mounted battery under the passenger seat!

Your car must be stripped down quite a bit, to be sitting at that weight.

Haha, true. I'm using the app, so I can't see anyones car on the left side. :/

When I had the 09 STI, I only got down to about 3140 lbs, full tank, no driver. Might of been able to do another 100-150 lbs... But it would have been a lot more money than I had already put in... Some more CF was needed, lol.

They're available from any auto parts store that deals with body work stuff.

Pro-Tek JMC001 is one type.

It's just a really tiny holesaw essentially. They're very pricey, but if you use LOTS of PROPER lubrication (not effing wd-40), go slow they should last a long time.
