Stress cracks on zodiac 733 fuel tank mounts.

Has anyone seen this sort of cracking around the mounts for fuel tanks on a H733? It doesn't seem like the structural integrity of the mounts are compromised, but sure looks like some torquing in the "false floor" in the fuel tank recess. Any ideas what should be done? Will probably grind it out and re glass, but maybe just a band-aid solution! I think that there may have been pressure or wait on the mount that has the worst cracking? Should of taken more notice, but did not see the cracking until I washed out the area. Out of the 6 mounting points , there are 4 with cracking around them. The pictures are by far the worst.

There is a 200 litre tank going back in there. The tank must weigh near 40 kilograms plus roughly 200 kilograms of fuel, so at a quarter ton, there's a bit of weight in it!

the tank that came out has the recess so it hooks on the 6 sections that stand proud. right?

Does the tank fit nice and snug? any movement fwd & Aft? or up, between top of tank and deck? i have never had a fwd tank in a 733? do they have a strap to hold them in place?

Yes,it's lag bolted through straps to those mounts, straight into the fibreglass. I didn't check if there was any movement before I undid it, but they were snug to undo! There did look to have been more weight on the 2 most aft mounts. I should dry fit it with the original under rubbers( which I did mark as to which came from where) and check for any movement. I can poke a scrib through in a couple of spots and it seems to be very thin fibreglass in those areas.Click image for larger version
