Clogged EVAP filter.

Clogged EVAP filter. - 11/10/13 09:18 PM

So I'm wondering. Does anyone else have this problem and how did you fix it?

On my 2001 the charcoal canister and valve and the filter for it all to breath is up under the jack compartment behind the rear bumper.
Now that filter is also how the gas tank vents when I put fuel in it (there is no other vent tube running up along the fill tube, I've checked many times.) The valve is open while the key is off and closes and does the EVAP recirculate thing when the engine is running.
And when I get gas you can see it pushing water out of the filter.

The problem is. It's wet and muddy in the PNW this time of year. I get about two runs before the box is filled with crud and soaks and clogs up the filter. Those filters are $45 at the dealer.

So every couple weeks I have the gas spit back out at the gas station and kick off the pump. and it can take 20 min to a half hour just to get 5 gallons in it. I can usually go home and clean it once or twice but after that it needs a new one.

I battled this all last winter and if I don't get it figured out I'm moving on to a different rig. <img src="/forums/images/graemlins/frown.gif" alt="" /> I love my Sportage but where I live and the type of wheeling this just won't fly.

I thought of more shielding to keep mud out from the rear tires and such. But it still needs to breath and that won't help when I'm up to the bumpers in goo/water.

I thought about a hose running to the engine compartment, relocate the filter there. But that is also looking like it'll have it's problems.

Why didn't KIA just keep all the EVAP stuff under the hood like that had with the single cam engine?...... <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

Guess they never figured people would actually take them off road and do water crossings and such.

Well I ended up going with the filter relocation.
It's up under the hood now. About 16' of 1/2" heater hose and few clamps and fittings did the trick.
Ran the hose above the frame until the point the body was too close and then along with the fuel lines.

Should have done that a long time ago. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

The charcoal canister was under the hood on my 2001 2-door. The rollover valve was mounted to the inside of the right rear frame rail at the back. Vent hoses went to a vertically mounted tube with a pinched top end hidden behind the fender in front of the right rear tire. It had hard line running from the back to the front along with the fuel and brake lines to get the vapors to the charcoal canister.

Yeah on the 4 door pretty much all of the EVAP system is behind the rear bumper.
Some hose to relocate it fixed it up though. If I douse that filter now I'll probably have hydrolocked the engine as well and have bigger problems. <img src="/forums/images/graemlins/wink.gif" alt="" />

Things have been working fine so far. <img src="/forums/images/graemlins/kewl.gif" alt="" />
