Fuel tank vent leaks

My vents still leak after replacing them, not much but enough that in a roll over I may have issues. I plan on making a cover for the tank but a fuel pool wouldn't be much better.

Anyone else have this problem or a solution? I imagine some might and just don't know. I picked up some fuel resistant RTV I'm going to goop around the vent.

The evap vents at the top? Did you replace the grommets too?

Yeah they have new grommets.
