I've never had a problem with them, I always seal them up with liquid electric tape when I'm done.

Most people don't seal them properly, they're particularly vulnerable to corrosion.

Troubleshooting an evap leak right now, its been traced to the filler neck area. Took the filler neck off and pulled down the large filler tube to clean the top of it.. and this fell out. Brass fitting of some sort. Question is, should this be in there? What is it? If not (which I suspect) how the hell does someone get it in there? And why?

It has a barb fitting for an airline on one side, I'm thinking it may have been related to the smoke test I had done yesterday.. The little flappy thing to keep debris out of the filler is broken, pretty sure it wasn't before.. I'm gonna bring the shop their part back and see what they say lol.
