Yeah, but it involves either removing the full fuel line assembly or cutting the EVAP line out, section by section. IMHO, I'd save this project for a time when you are replacing the fuel lines or dropping the tank.

I've just done this full delete on my 2005 race STI. I found this breather for the rear, it fits perfect and is very compact. 3/4", Rubber Top.
S&B Filters, 26-1519JR

I was worried my garage would smell of gas fumes after this but nothing. No fumes smell. At least no more than usual!
Great thread, thanks.

Did you do anything with the lines that are red in the photo below? I think some folks just connect them together? I believe the yellow line is the vapor feed from the charcoal canister up to the intake manifold. I think the blue line is the line you have labeled as "B" an needed venting (with a small breather filter). Seem correct?

Is this mod safe for those storing their car in a garage with a quartz heater if you leave the line to vent to atmosphere?

Good question, I keep reading something about T-ing lines together at the filler neck, perhaps that are these red lines?

The red lines are the roll-over breather valves and are already tied together... the white 'T' is clearly shown in that photo. IIRC, the red lines travel up the filler neck to a valve that responds to a filler being inserted at the pump. The line that leaves this valve then enters the charcoal canister. With the canister removed, I stuck a Fram in-line filter on the line leaving the filler neck cut-off valve and hid it behind the plastic filler cover.

The yellow line is the EVAP line from the charcoal canister to the engine.

The blue is the large vent line to the charcoal canister. I stuck a filter on this one too - larger than the first one.

I envy the JDM setup... it's infinitely more simple than the crazy regulated fuel tanks that get worse and worse every year in the USA. There is literally one hose that travels to the filler neck, and one small hose you stick a filter on and you're done.

Posting from another thread I commented on:

For anyone doing the delete, you can easily have the CELs for the evap system turned off by a tuner. Most won't charge, just be nice and ask. You can typically send them your current map and they'll make the changes in Accesstuner and resend to you. Just make sure they also force ready the evap monitor too (or all of them while they're at it).

Any yes, this will pass inspection, however, just like you're "not supposed to remove your cat" no one can really tell.

Serious question though, wouldn't most inspection stations be able to see the missing black box and tubing with a breather valve? It clearly looks like equipment is missing.

I've had no issues venting mine via the line that runs to the turbo inlet. You only get a fuel smell when fueling, which you can smell outdoors. I would not recommend filling your car indoors via a gas can with this modification and a heater on.

You don't need a tuner if you have ATR - takes ~5-10 min to disable the DTCs and reflash the tune.

If you cannot force readiness, the disabled DTCs will ready the monitors after a drive cycle.

Funny you say that.

I actually thought the same thing, downloaded AccessTuner, loaded my map, made the easy changes, then resaved. Loaded it to the AP and....

When you go to reflash it, the tune is greyed out and not comparable. Apparently you need a serialized version of Accesstuner to do this with any Cobb maps for sure. Not sure how that applies to other tunes. I'm sure OpenSource is more friendly for this.

So I have the Evap delete done under the hood. I'm gettting the P1420 code which is the solenoid. Would this affect my car at all?

For anyone wishing to do this in the future, if you are not able to disable to codes right away and don't want any check engine lights...

In the engine bay keep the evap solenoid connected to the electrical harness but no hoses connected to it. For the rear charcoal cannister etc. Keep the electrical harnesses plugged in and connect the hoses to each other but not hardwired to the car so the evap system isn't actually operating but the car thinks it's still there.

If anyone needs pics I can go take some cause I'm not that great at explaining things...

Very informative write up. Thank you. Nice to see a dead thread raised due to questions.

If you are open source you can delete the codes yourself, mine were super duper nicely labeled and were able to be turned off and were in a larger section around the p0457 area (turns out the previous owner disabled my system about completetly but left **** plugged in??? but did the most half ass job I ever seent :un amused:)
s'ok nah


thanks for the writeup though, components are on the shelf next to the hoard of stock parts.

It's not just you - Photobucket decided to give everyone on the internet the middle finger about a year ago.
