During camshaft installation I managed to split my tandem pump key in half. Welded it back together it’s running and driving perfect now, but I would much prefer to have a new one. 2006 brm Jetta, I called the dealership and they don’t sell it apart from the tandem pump. I’ve done some digging and can’t even find a part number for it. Anyone have any leads or a bad tandem pump they wouldn’t mind ripping the key off of?
