Recent tropical storm dumped a lot of rain with driving wind on our marina. We were told by the Marina Manager that we had fuel coming out our overflow on the stern. He went on board our 1986 Hunter 31 and found the cap to the fuel tank to be loose. He recommended that we drain the fuel tank before trying to start the engine. Does anyone have any suggestions on the best way to do this on this boat? Ideally we would like to drain from the bottom to get the water first. We do have a water separator on the fuel line.Prior attempts to drain through the fill line have been unsuccessful.
