08' BMW 528i 3.0L I smelled fuel coming from the back of the car, checked underneath, the sending unit was leaking. I replaced the sending unit (behind the driver side, under the seat) I cleared the code before driving it,and the check engine light came back on with THE SAME CODE!!!!! =( I hear a hissing sound but the fuel is leaking! I hear the same hissing after you (Nathan) replaced the fuel pump. What the hell is going on! If anyone has advice please let me know. Tomorrow I'm going to take it apart and make sure that the seal, that is NEW is on there correctly.
