charcoal canister in a ej22 swap

[johnceggleston]

i'm swapping an 95 auto ej22 into a 98 outback. the 98 has the canister in the rear and the 95 had it up front.

 

to simplify the plumbing, can i just install the 95 canister in the front of the 98 and hook it up like it was? will this cause me to have "open" vac lines in the rear?

 

are there any "sensors" located at the canister in the rear? or is all that stuff still on the strut tower? (looks like it's still all there.)

 

if the rear canister is still "plumbed" in at the rear, will it hurt to add a second one up front? adding the canister seemed like a simple way to fix the plumbing.

 

this stuff is a huge mystery to me, kind of like the smoke in the electrical components that you don't want to come out.

 

EDIT, i read up on this in my haynes manual and have a very basic undetstanding of the system. i guess the big question will be if the solenoid is connected to the correct vac line. and second, do the metal lines need to be connected to something specific, other than the front canister. don't see any real harm by having 2 canisters. would be possible to connect the front "canister" lines on the ej22 to each other, just make a u-turn, to complete the system without the front canister?

 

any help would be appreciated.

If the vent line coming from the rear of the car is coming from the charcoal canister, then yes all you need to do is connect the two lines in the front with a hose in a U.

 

I'm pretty sure the vent line coming up will be coming from the charcoal canister vs. directly from the gas tank.

Just switch the intake manifold. No check engine lights, and honestly pretty easy to swap. You can leave the coolant crossover pipe as its the same except maybe the coolant temp sensor(s)....can't remember off the top of my head.

 

Its worth the 10 bucks in gaskets to have the car right.

Just switch the intake manifold.

 

i would if they were both 2.5L engines, but one is a 2.2L and the other is a 2.5L. i don't think they are interchangeable.

 

but maybe the underlying "tubing" is?? anyone know?

It's possible (and IMHO, best) to keep the existing rear charcoal canister. I did this swap and just did a little loop between the two tubes on the front of the 2.2 manifold/ vac pipe assy which would have been connected to the 2.2's charcoal canister. I think I may also have added a "T" somewhere and plugged a hose. It works with no CELs. If you're not in a huge hurry, I might be able to work up a diagram or shoot a photo. It's definitely doable.

I keep the rear canister.

 

I also believe a T is needed on the intake IIR to tap into the rubber lines.

 

Been a while since I did a swap. But I always leave/use the original canister and play with the plumbing to get it to work.

I've always installed the front from the 95, but also leave the rear in place. No Cels.

 

You just need to grab the canister and bracket. The holes are all there.
