I have a 2011 (completion date) Factory Five Roadster Mk 3.1 with a 351 Windsor engine. The Mass Flo Fuel Injection includes a pump inside the gas tank. Recently, I noticed a fuel leak behind the passenger seat. I've removed the tank and unconnected the fuel lines. I don't see any evidence of a leaking connection or other obvious source. Could the rubber fuel lines, housed in braided SS wire, be deteriorated, cracked and leaking?

Anyone else have similar problems? I'm looking for a solution without randomly changing the fuel lines. I'm prepared to do that, but I'd rather have more confidence that the lines are the problem. This weekend, I'll finish my trunk box installation (yeah ten year late), and re-assemble. That'll give me an opportunity to "see" the leak better.

Thanks in advance,
