Dropped the fuel tank on my 2006 s40. Had a leak coming down the side of my tank. Got it down to realize that the electrical connection was saturated with fuel but no residue around the lock ring of the fuel pump. It does look like it is coming from the "breather" I assume. There are two of them coming out of the tank one by pump and one by filler neck. Want to kno wat they are cause I think one by the pump is leaking and I broke the connector for the one by the neck.

 

this is where I like to go to web sites like Tascaparts.com that have diagrams and part numbers...
