caused a kink in the side of the tank which caused it to crack over time. So $473 and 2 hours of labor later had the tank replaced.
Dude, plastic weld it up. If it was plastic that is. Did you get the replacement Rolls Royce part or what? LOL

My original plan was to plastic weld it. But were the crack in the side of the tank it sits on a bevel on the tank between the top and the side of the tank. When the mounting strap was overtightened it pushed that flat bevel inward basically caving in the center of that bevel.

First picture is suppose to be what the tank looks like, second is what happened when the clamp strap pushed down on the top of tank.

So there is no way to prevent the pressure from the strap from trying to push the bent area inward recracking the tank. Also the tank also has stress cracks around the fuel level sending unit hole mounting studs in the top of the tank. Keep in mind this is a 15.3 gallon tank from a 45 HP tractor

I know you are more than smart enough to skin this cat.

Grind threads off the strap as to not over slam the threads and eventually warp the tank. Thread locker will help here. A strip of pipe insulation or foam double sided tape under the strap. Something to buffer the tank from movement. Weld stopping or bottoming out nuts to the strap so you don't over torque it again.

Make a wider strap that mounts in a different spot?? Tack on some all thread and go to town. Add another strap 90 degrees off from the original strap.

You can hammer down or flatten plain old electrical cheap conduit to make a strap. Weld on as mentioned all thread for threads. Tack on travel stopping nuts. Thread locker.

Bungee cord from that Z bend metal tank holder plate across the tank. Put about 8 bungee cords on her. She will never move. Gorilla tape the sucker down LOL. This ain't the space program as Taryl says LOL.

It comes down to how much time do you want to tinker with trying to get it right, when everything I posted in the diagram picture fits inside of the tank mounting frame.

That has to be removed and reinstalled with the tank. That entire empty tank with its other parts all bolted to the heavy frame in this diagram. The entire thing weighs around 50 pounds. Which is bolted to the tractor frame behind the loader mounting brackets.

May just take a few fender washers to prevent the over tensioning of the tank strap.
