Difficult refuelling 101. A quest.

If anyone is interested, I am documenting my "difficult to impossible" refuelling problem over here:

Changed gas tank bleeder valve, now it won't fill! - 986 Series (Boxster, Boxster S) - RennTech.org Forums

Here's the first post. Feel free to chime in. I need all the help I can get!
And yes, I have used the search tool.

In the "If it ain't broke" category.
Symptoms:
Hard start when warm, after sitting for 15 minutes or so; intermittent Coke bottle sound (low whistle) at low speed. No problems fuelling car.

Attempted solution:
Changed bleeder valve, also known as fuel tank ventilation valve 99620114301. This valve is not electric but mechanical. The gas cap, when closed tightly, pushes a little piston which opens the valve to recirculate the vapours.

Result:
Can't put gas in the car! Takes about a litre then spits it back out at me!

Okay, so I have obviously up royally here. So I tried putting back the old part. Nope. Poked my finger in the filler flap: No click (should there be one?). Checked the E6 fuse. Seems okay. Could it be another valve/switch or what? And what have I done to cause this, aside from fixing something that wasn't broke?

Solved!!!

Thank you Gelbster for this link!
In fact, it was the magnetic switch which was not inserted into the space provided for it in the valve. It had fallen out when I pulled the old valve but I didn't notice. I did see it but couldn't find any information on it until I saw this post.
Thanks again!
