Gray Water Tank Leak After Tire Blowout

I have a 2012 Raptor 300MP and had a blowout on the front, driver side tire. I removed and replaced all the 3" ABS pipe up to the 3" wye under the coroplast. The black water tank is fine. When the gray water valve is closed, and the tank has some water in it, it begins to leak around where the 3" pipe goes into the tank. When I take off, water pours out from underneath the trailer.

Does anyone know if there is any kind of caulk, sealer, or epoxy that I could put around the 3" ABS pipe where it goes into the tank? It appears to be a black poly tank.

bevtha... there are some Youtube videos targeting RVers and the poly plastic tanks we own for tank repair. Almost every repair I watched in the video required the tank to be pulled. I will share one with you...do a Google search to find more. they are interesting and may lead you to other thoughts and repair techniques.

FYI - ABS plastic and all types of "plastic welding" - I've found is not terribly easy. Might be OK with a combination of welding and appropriate sealant...

Vibration will be an issue limiting repair. J B Weld might be effective. You might find some type of plumbing flange you could glue over the leak and adapt down to the desired size. Have you called the ins co? A new tank would be good.
