I have seen (via email and phone) this several times. I have a warning about it in my 370z fuel pump mod PDF.

I usually recommend attempting a heavier coat of PTFE thread sealant. Tank replacement is the only true fix. But if you can get thread sealant (gasoline compatible) to stop the leak, then it won't matter until next time you have to service the pump and deal with it again.
