Leaking FW tank

[RandMadeRods]

Has anyone with a FW holding tank (FW washdown) had a leak problem? Mine has a slight leak somewhere, I don't think it's the tank itself, and have checked all the visible clamps. When I fill it up prior to a trip, I can see a slight trail of water traveling from behind the tank along the rear of the PH and into the drain to the bilge. It's not alot, maybe a couple of ounces, but I want to remedy the issue. I also don't overfill the tank, leaving an inch or two as visible from the side. I also ensured that the screw opening on top is tight. Any suggestions? Thanks, Randy.

I have not
You can add food coloring to help find it

I would suspect the exit connector going to the pump. If that is not the problem, then the tank has probably developed a crack in it from not being tied down tight enough...the rocking back and forth due to boat motion could cause the tank to crack.
