I'd contact a reputable manufacturer of polyethylene tanks and ask them.
One of the best, and the supplier of SeaLand and many other holding tanks, is Ronco Plastics. They're a great resource:

The best is to replace, in the short term a couple options.
Clean outside of tank scuff area and dry, 3M 4000, or even 5200 (the evil stuff) place a patch over the area.
If the discharge is not under fluid level:Relocate with an inspection plate and new through hole...
I could not find a regular poly tank to fit my application, so I made on from fiberglass and epoxy resin. 12 layers of glass, 3/8 to 1/2 thick. All access holes are in the top. SO far so good.

|wchevron||i think if the fitting is cracked, your out of luck. if you have the room and it's on the top, you could cut out the fitting and install an inspection plate in it's place. then get a hole relocation kit for a new discharge hole. if you end up getting a new holding tank, call ronco-plastics.com. they have about 200 different sizes and you can specify where you want all of your holes plus their tanks are pretty thick.|

Holding Tank Leak :(
My polyethylene holding tank has a very slow (thankfully) leak where the fitting for discharge is inserted. PO had macerator connected directly to HT. I think the weight of the non-supported macerator might have ruined the seal. I have tried caulking to no avail.
Anyone have serious remedies for this? Non serious are welcome as long as they include something helpful. Is it possible to "weld" the plastic fitting to the holding tank or is it best to start over?
