When under the car there are 4 lines that seem to run from the fuel tank to the front of the car. If you are looking forward, the two smaller lines on the right always leak something after I've parked. I'm not sure what it is and is this a bad thing? It doesn't smell like gas but could be.

 

Touch it and smell it. It could be simple condensation. You will not miss smell of gas.

 

It doesn't smell like anything. If it's condensation, why would it always form in the same exact place? I don't see any a/c lines that run anywhere near there.

 

Are you sure its not the ac condensation coming out of the drain tube and running down the lines.

 

I'm hoping it's a/c condensation but I can't really see any lines where it would be coming from. I guess that should have been my original question: where does the drain tube empty out at?

 

if there is no smell its just the ac condensation and yes it comes from the same spot

 

Condensation may form on any lines which are hotter than air temperature. So if whatever is dripping looks, feels and smells like water I wouldn't worry about it.
If it feels sticky or smells funny, then I would have my car examined by mechanic.
