McShank Posted July 6, 2010 Share Posted July 6, 2010 JohnW, Years ago I owned a Dolphin with dual tanks. There was a toggle switch on the dashboard to go from main to aux. tank and when on aux. the fuel would drain into the main tank until empty - the engine kept running because it pulls from the main tank only. The fuel gauge would read the level in whichever tank I switched to. I never had reason to trace the lines but figured the aux. tank was mounted higher tha the main one and there was no pump, just gravity feed. Hope this helps.
