Turbojimmy used this to repair a fairly old and cracked black tank and is happy with it.

So rev might not b the best choice? What would be a good choice for the ABS?

Make sure to use compatible products if you try to fix it. Not much will stick to the ABS and once you get it gooped up with the wrong stuff, you just made it much harder to fix with the correct material.

You might try gently pushing and prodding the tank. A hairline crack can be very hard to see, particularly in black material in the shade. A little flexing can open up the crack and make it easier to see.

Silicone may let go under the slight pressure. It's an ABS tank so I would apply several coats of ABS cement to the area.

Thanks!

clean the area heat it up with a hair dryer and apply several thin coats of rtv allowing to dry between coats

Well it does have a black tank flush (which hasn't worked in a while) - but maybe they put it multiple locations for various routings into the same tank?
Any thoughts on fix the leak/seap?

my guess a spot for the mold or a plug for where a tank wash would go
