i can smell gasoline the next morning after she sits in the garage and my tech tells me i have a leaky injector. Or is the o-ring?

how can I tell if its the injector or the o-ring? and can i get this fixed somewhere other than the dealership?

 

Mine does that, but it seems to be coming from the charcol canister.

 

It must be an o-ring on the injector, I don't think the injectors themselves are prone to leaking.

You can get them cleaned and flow tested with new o-rings for $80 to $100 for all four at any fuel injection service shop, but you have to take them in. It's a pretty easy diy job. Make sure it's not your fuel line, several cars have gone up in flames for that reason.
