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.
Thanks phunk. I didnt smell gas anymore after an initial test, but then i think i ran into other issues and the tune or maf code caused a rich condition bringing fuel smell again. Ill try the PTFE thread sealant and see if i have any luck.

Wish i had the info on why someone switch the screws out to begin with!!
