Yes, they are the 6.354's. I changed the filters around 100 hrs ago. I'll wipe down the engine and check again. The tough part is that all the likely spots for a leak are on the outboard side, next to the fuel tank. Not a lot of room to squeeze in and observe.
Lay some oil absorbent pads under the engine so you can at least determine which side it is coming from and about how far back on the block.

The two areas I usually will have leaks from most often are:

The fuel outlet line where it leaves the lift pump - No gasket there, just a little flanged end on the metal pipe. *If they are under tightened they will leak and over tightened it will crack the flange, leak, and then must be replaced. Of course if this is the Starboard engine, that would be on the outboard side. *Murphy's Law!! *

Either the gasket on the tensioning bolt or fuel filter canister gasket on the secondary filter. Both can be a problem.
