I had this problem and it was traced to copper washers; they get compressed and fuel drips down into the bilge

The first leak was in a flare fitting in a copper fuel return line that work hardened due to vibration. The flare cracked, and had a small leak. Moral 1: Copper fuel lines suck. Use rubber. Moral 2: Always put a spiral coil in a copper line adjacent to any flare fittings to absorb the vibration. The second leak was a pinhole in the bottom of the stainless fuel tank where it sat on a wooden platform. Moral, put in rubber pads to space the tank from the platform so there is no crevice corrosion form trapped moisture. As Bill Coleman suggested, put a bit of paper towel around each fitting. You will find any leak pretty quickly. And if the engines does not shut down while running because of air in the line, look especially hard at the fuel return connections.

When I run my bilge pump, I do see some slight rainbow coloring in the water. Before I go checking everything out this weekend and disconnect any hose clamps, is there anything that I should be careful about (letting air into the fuel lines, etc.)? Would appreciate any advice from anyone -- especially from those who have experienced and fixed a similar problem. All the best, Edd Edd M.
