I've been experiencing a fuel smell for a few weeks now from my engine when it'* off after running. I've replaced the Upper Intake, gaskets, and new injectors all the way around and while the smell is diminished somewhat, it still smells. What else should I take a look at?

Might take a close look at the fuel pressure regulator and the vaccuum hose that connects to it.

perhaps a charcoal canister is bad / disconnected?

Got home tonight and the smell was stronger than it has been. Used the ol' sniffer on the front of my face and it led me right to the vacuum hose line from the pressure regulator to the top of the UIM. The smell was so strong it burned my nose hairs real quick like (southern for really fast). That'* the last component that I've not touched (I'm cheap, didn't want to spring for the pressure tester). After 203k on the thing, I guess it cold use a new regulator!

Thanks
