Hello, From the factory in our 2012 Hunter 50AC there was a 2nd fuel tank under the galley floor. It has a fuel line going to the aft fuel tank and there is a small breaker saying fuel pump on the major panel with the main battery switches under the seat ahead of the galley. I want to transfer fuel from the extra tank to the main tank, but pushing the fuel pump breaker in doesn't seem to do anything and I don't hear any fuel transfer. Does anybody know how Hunter set this up ???? Or who to contact to ask ??? Thank you very much Derek
