If you can see the mount to the tank easily, pull it off and see if the holes are stripped. If that is the case, a next size larger screw might do the trick. Adding a sealant to the screws when installing could also help. You need to figure out why the leak and where it is coming from before trying to fix something that might not be the problem.
