2001 Tiburon (yep, this one again): Gassing up clicks like it’s full, even after only a dollar, then keeps clicking. Tank is at an 8th when fueling and yes, i’ve made sure it’s not the nozzle (and does it no matter where I go).

OBDII code PO441 Small Evap Leak (changed gas cap, no difference) Had a buddy pull the charcoal filter from the back of the car and cleaned it out, no difference. Becoming a big pain in the arse now since every time I gas up it spits out at me and takes literally 30+ minutes to fill up.

Please help!

No offense to Mr. Tiburon Guy (he seems cool) but this query is precisely why we have message forums. P0441 is a code you type into a forum/search engine and get an immediate answer.  I like this website to get the ball rolling. It gives a good description of the problem(s) and the systems involved.

Once again, more shame: you just threw away money on a new gas cap for no good reason! I know it was the easy thing to do, but it wasn’t gonna work.  So here’s the deal, a P0441 code means several things:

1. Blocked up charcoal canister, perhaps cleaning the filter was never gonna fix anything?

2. Blocked or bad canister purge valve, or the vacuum/electrics behind it are toast. This is my guess to your problem. 

3. Physical damage to venting system, or fueling system.

A quick bit of googling came up with this thread on Hyundaiforum.com; mandatory reading before doing anything.  Then find a similar thread about the Tiburon instead. Once you have all the right information, examine the system for damage and follow their instructions.  If all else fails, buy the shop manual(s) and do it all step-by-step from there.  You will find your problem.  Best of luck.

    The Taurus Car Club of America forum is the first place I go when I have questions or issues with the Blue Goose. Last Friday, it lost 2 quarts of transmission fluid (most of it all over the driveway) after a 2 hour drive in rush hour in 103 degree heat on the way home. After panicing, I asked on the forum, and determined it was a worn torque converter stator bearing; when the transmission gets hot, the fluid gets thinner and leaks out past the bearing. I added two quarts and drove it around town; no leaks, and none in coming this morning in 83 degree heat. So, that is probably it; thank God for the TCCA forum and that the heat wave has finally broken in our part of the world.
