Took my Porsche Boxster to the local Porsche dealer for an oil change. They called me back and said my car had a gasoline fuel leak and needed a replacement fuel level sensor it was cracked and leaking fuel. . The service order at pickup said mechanic noted fuel dripping from gas tank. . . Noted leaking from cracks in the sending unit where the pressurized fuel outlet is, replaced sending unit and seal, also noted electrical connector seal swollen from fuel contamination. I asked the service manager if this had been reported to the NHTSA and he said no, why should they. I exlplained this was an extreme safety hazard involving a fuel leak that could have serious life or death consequences. I have the replaced unit and pictures as I requested this upon picking up the vehicle. I was charged $628. 58 for replacing faulty fuel level sensor(sending unit). I have a copy of the bill with mechanic's comments. Also pics of the faulty unit on my cell phone.
