Repairing a plastic water tank

[Boomerang]

I have a 250l plastic water tank that is showing early signs of the start of a potential crack . It's not split yet but looks like it might .next week.next month .next year.
Any tips on how to prevent this getting worse. It s 100mm long and is where bracket holds tank to frame.
I've padded out frame to protect it .
Any ideas on proper repair??

It's on a little yard sprayer but also used from time to time to cart water about .

That 2 part plastic padding type epoxy mix together stuff good if slight crack possibly.

Gripfill followed up by silicone sealant. Seems a shame to replace if it can be mended for a few pence.

If it does not flex much fiberglass might do the job

Drill both ends, groove it out to fresh plastic and borrow/buy a plastic welder. Did our old sprayer tank and it’s still going strong as. Was tight on the clamping band too. Don’t use it any more for chemicular jobs obviously
