Success! Finally fixed the hard start while hot and fueling issues.

Great info,I have not had that problem with my 06 Boxster s but my winter beater a toyota Echo did,couldent get fuel in tank,ended up bypassing the charcoal cannister and voila works again,but gasoline fumes will come into the garage now if its left inside.I was told that this problem with fuel not filling and destroying the cannister or parts leading to it is trying to over fuel the tank,fuel will drain back down the overflow into the cannister and destroy it as its only ment for fuel vapours,so when the pump clicks full,pull it out,dont try and squeeze that last few dollars in.

I am having the very same problems, every time I fill up the tank I'm having a hard time to start. But no problem at all with hot engine. The valve you are talking about looks like this?

I just changed the regeneration valve on my wife's 00 Boxster using this post!

It cleared up the hard to start problem after the engine was hot and after gassing her up at the pump.

I would like to inform those that want to not have to crack the clamp / housing that hold the regeneration valve up to the manifold - use an 8mm wrench and take deep breath. I got mine off and back on.

thank you San Rensho for an excellent post.
