Honda EB-12D Diesel Generator spraiyng diesel?

Hi. I have a Honda EB-12D Diesel Generator. When turned on, it is s"spraiyng" what appears to be diesel from a "coupling" at the top left area (inside the air intke grill, at the front of-but very close to the muffler. The diesel sprays from such area, and a little even collects/pools inside. I thought I have overfilled the diesel tank, but removed approximately 2 gallons, and the issue continued. Is this not normal and dangerous? Do you have any idea what would be the cause? I would really be very grateful for your oppinion.
