2002 SLK320: The seller said the top was working, they were driving it around until the fuel pump failed and they pushed it into the storage lot. When the car arrived the top pump was empty, maybe a tablespoon of fluid at the bottom. Unless the seller was lying, the fluid had to go somewhere, either pumped/squirted out, leaked out, or evaporated. I really doubt it evaporated, so I need to know where the leaks are most likely to occur so I can have a bucket under it. For what it's worth I can find no evidence where the fluid may have gone, though a year or more in the hot Florida sun can do that.
