I was just about to say if its plastic tanks you can make your own fixing point yes. The more modern standard versions don't have a thread anymore just 3 legs a gasket and self tapping screws. You can make your own on metal tanks but would really have to be empty to avoid cutting sparks. The old versions had thread on the bottom so could screw into a socket and also a flange nut which could be used if the inside could be accessed. We still do the version with the thread on the bottom and flange nut but these are more expensive now as we still have to turn the base on a CNC machine fully to make it rather than just machine the casting.

you can use the 3 leg modern version on steel tanks if using self drilling bolts, and the mentioned cutting the hole when the conditions are correct for it!
 
Tank if forty years old so think it's out of warranty by now, but thanks for your concern. 🤔

Just in case, it is not porous and has not UV degraded. 😇
