Fuel tank leak - Advice needed

I have fuel slowly dripping from my fuel tank. I got under the car and it is at the two hoses, I believe they are a vent hose and return line. I replaced these last year so a was surprised to see this show up again. The hoses are not cracked, that I can see. There is a rubber squishy membrane that is cracked and wet with fuel. I am guessing that the fuel tank sits on this membrane. The hose clamps are not loose but maybe a hose is cracked on top where I cannot see it. Perhaps I tightened the hose too tight last year and cut it. The main fuel line coming down from the tank is completely dry, BTW.

My question is, is there anything above these two rubber lines that could be the source of the leak? The leak appears to be from the rear end of one of the hoses.

And IIRC, the hose is 5/16", yes? EDIT: Just read another thread and it sounds like 3/8" is a better match for the 8mm or so OEM metric hose. A number of people report problems getting 5/16" hose around the metal lines.

Thanks for any input.
