New water pump instal leaking

I put in a new water pump on a 2003 Durango 5.9L using a Fel pro gasket.

The gasket is meant to be installed dry and clean, so that's what I did. I usually put some other sealer along with a gasket and don't have any leakes. Didn't use sealer this time and it didn't work out so well.

Right now the pump is very easy to get to, so I was thinking to give it another try with no supplemental sealer, or should I just run a bead of silicon on both mating surfaces along with the gasket.

The old pump did not have any other sealer.
