I've seen multiple posts here and the facecrook groups over the years about the baffle coming loose.

Same thing here on a brand new tank a few years ago. Took it out and round canned it. Felt it would be more trouble to glue it back in as the poly plastic IMO has been hard to get a STRONG bond. So the fuel slooshesssss around.

Sloshing fuel is a very bad thing at low tank. Air in fuel can cause stalled engine at speed.

I would absolutely repair.

I don't think RTV would be good enough, a good epoxy would be my answer, and as DREDnot stated I would buff (lightly grind) all areas to be epoxied to expose a virgin surface.

The sump doesnt get much stress other than expansion or sagging with fuel weight while slamming with the stiff suspension. Thats why I would use four big blobs of RTV to fix it in place like the isolator pads on a radio mount. The intake and return pipes keep it in place even when broken loose and between sloshing fuel entering the slot and returning fuel the baffle box still functions as intended.

I initially contemplated epoxy or jB weld but I pictured whatever forces broke all those plastic spot welds might just as easily crack the harder epoxies
