I finally did this. Can't believe it took me almost a year since my motor rebuild either.

Did you find the $90 one? I swear I saw the other one which hooks up to the canister in the rear of the car...but I looked now and can't find it.

Yeah, it was the 90 dollar one. I'm pretty sure that's the part I need.

I was actually thinking its this: http://natemichals.com/wp-content/up...707_190215.jpg

The canister vent valve, not the purge solenoid.

I have noticed what I thought was an exhaust leak on cold start. After lifting the turbo and check both UP gaskets, and all exhaust manifold and DP gaskets, I haven't found any leaks. I'm beginning to wonder if the "leak" is simply gas fumes coming up into the cabin on cold start. I only really notice the smell on cold start when the HVAC (heat) is turned on.

The gas tank vent hose near the firewall has been extended, and it routes to underneath my car. It exits right near the rear mount for the *front* control arm on the drivers side. This is pretty much under the drivers seat almost, so I'm wondering if this has been my smell all along. My shop removed this solenoid in the first place because they claim it can leak, and that they remove it on all cars that see competition. (autocross for me)

I have the correct CEL's turned off of course, and I have the proper caps on my AMR inlet, and on my intake manifold. The "hard" fuel line under the intake manifold is simply left open, since nothing is connected to it on either end.

Thoughts? I thought I had an exhaust smell all along, but maybe not.

Acejam2K - If you smell fuel fumes, like you would when filling up with gas, then chances are it is coming from that vent line. An easy test would be to extend the vent hose back to the gas tank area and see if the cold start smell still exists.

Can the hose be disconnected at the gas tank? Doesn't the hose at the firewall originate from that charcoal canister?

I'm not certain. Keep in mind that you may always have this fuel smell since Subarus are not sealed as tight as a submarine. I'd prefer to see the solenoid installed and functioning since that would eliminate the smell. I'd remove it on a race track only car, not daily driver.

Thanks IA for the help. If I were to pickup a new solenoid and install it - would that throw off my tune? I wasn't sure if the fumes being sucked into the inlet would be considered "unmetered". For what it's worth though, the smell doesn't entirely smell like fresh gas at a gas station - it smells more like exhaust.

Are there any MPG effects on removing this solenoid? I've noticed my car has always had a slightly lower MPG, but I think that might be due to my heavy right foot.

I do not believe it will throw off the tune. I'm learning more and more about the overall evap system. I've tuned cars both with and without these sensors and they both run very similar fuel maps.

I believe so. The best way to check would be to call your local dealership on Monday and have them look up the part number for your VIN and then give them the VIN of a 2003 WRX (grab it from a car on eBay). If the numbers match then it definitely will work. I know both models are identical in appearance and plug size.

I would like to revive this thread and see if i can get any help. I have the same problem as Striker on post #50.
I have 07 Wrx throwing code p0457. Idle is weak -dying then goes up and down. Also car stalls - shake very bad after pump gas. I checked the T hose they all connect and all other hoses I can find but everything seem okay. I was wondering if you have that diagram for wrx 07 jdm /delete hoses to prevent/ stop evap cel ?

Please reference this thread:
http://forums.nasioc.com/forums/show...1#post39456471

Although, it does not contain the answer regarding deleting the 07 purge solenoids. If I were you I would do a "boost leak test" to identify the leak. Since the car is idling poorly then I imagine there is a loose hose or broken nipple somewhere. The "boost leak test" will show this.

Do the "boost Leak test" and then report back with what you find.

Ok, deleted the purge valve on my '03 and I'm now getting the P0457 CEL. This is a new CEL 100% related to this mod, which was very helpful in straightening out some of my A/F Learning concerns.

Can I have my tuner safely disable this CEL code via the AccessPort or is this an indication of another issue?

I'd consult with your tuner. They are the only ones to determine if it is safe to turn off.

Just saw this old tidbit I posted and thought I should clarify. I didn't mean to run a hose from the firewall hose to the manifold. Rather, replace the metal line in the stock fuel rails with rubber fuel hose and hook that up to the purge assembly where the metal line used to hook up.

Okay, I've just read through all of this and as I read it I can completely delete the purge control solenoid and EGR valve as long as I vent the fuel evap line to atmosphere and bung up all of the take-off nipples. I will need to get the solenoid fault codes turned off by my mapper though - is that correct.

If it is I'll be cutting off all of the take-offs on tha manifold and welding and smoothing them as I've done with a load more lugs and take-offs...
