That sweeper elbow in the foreground of the picture probably should be supported. When the pipe is full there will be significant weight on the tank joint bouncing down the road.
If you go with ABS cement repair.... skip the screen and get some thin sheet ABS and roll it to make an envelope around the pipe. Heat gun will do the trick. Gob it up with Plastic-mend and use a couple hose clamps to hold it in place while it hardens. Keep the end gap narrow and fill with more Plastic-Mend. And of course clean and prep the area.
