Bob,
Bob, you are correct if a fuel dock did this. But in my area, and every where I have been in the last couple of years, no fuel dock will put the fuel in the boat. Around here, they hand you the fuel hose, and you pump your own. The reasons are the liability of spilling diesel. Even a small spill of a few drops and get you a hefty fine, if spotted by the wrong/right person. So the fuel docks I frequent, require the boater to pump his own. Another item, along the same lines. When I went with Clewless, Seadance's hubby, to pick up their boat last month in Fla. we were filling the water tank. Seemed like it took a long time to fill, and then we saw the water. Pouring out of an overflowing head. On first inspection, it appeared that somehow the water fill was tied into the head discharge. Closer insection revealed that the head pump out fitting, had a water fill cap on it. So there is more than one possibility here. Lets not jump to conclusions.
