just because there are no leaks, does not rule out that line. On multiple occasions I have had the metal fuel lines before the lift pump rust out on top and suck a bunch of air but they didn't leak .Since there is not a lot of pressure there, it won't always leak, but it will suck in air. It could also be a fuel pickup in one of the tanks fell off.
