See top/inner line at lift pump and right side of S/O valve viewed facing it.

If the photo of the line to the pre-filter was taken with engine off that is fine. If taken with engine on you have a bad seal at one or the toher end of that line, or beneath the pre-filter itself. If engine was on fix that one first.
