I moved somethiing on my filler pipe and now the car won't take ga

I've been working on a odd sound coming from my fuel tank cap area and I mistakingly moved a funny looking item that I now believe is the trigger unit for the gas tank vent valve. Now my car won't accept gas when I try to fill up. Here is a picture. Can anybody tell me exactly where it's supposed to go?

I figured this out and fixed it yesterday. About a week ago I replaced an item Porsche calls a vent valve near the filler cap. The trigger unit actually fits inside a recess on the plastic housing of this valve. I didn't realize it when I took it off (the plastic housing broke while unscrewing a stuck bolt and the trigger unit came loose at that moment without me noticing). Anyway I'm back in business. Here is a picture of how these two parts fit together. BTW you get a new trigger unit when you order a vent valve. I thought the supplier made a mistake and I actually thought the trigger unit was a brake pad sensor that escaped from somebody else's order.
