Yes - the original picture was in fact a connection into the wall of the fuel tank. In this last photo it's a bit blurry but that's the same connection point.Not a problem. That would make it a return line to the fuel tank rather than a feed line to the fuel filter. It's more complex now because there are several lines, but it is still a low pressure line filled with fuel that has leaky age cracks in the rubber.
There should also be a hard steel line to each injector. See if you can get a picture of the complete injector - best to do them all.
Also, we originally assumed that the upper right hand side in your first photo was a connection into the wall of the fuel tank, but we ought to confirm that.

Yes I believe it's the same style fitting as what is up at the fuel tank as well. I couldn't get a reasonable photo today since the sun wasn't shining out here in the northeast!Hard to tell for sure with wiring loom over fitting in the picture but it almost looks like a banjo style fitting on the engine side?
