Does anyone know the internal structure of the Ultimate fuel tank?

A couple days ago during preflight inspection, the rubber seal of my fuel cap fell apart and I think a few pieces of rubber went into the fuel tank. I was not anticipating such thing to happen so honestly I only saw some black shadows in a split second. Since I couldn't really find the parts on my hangar floor I'm assuming they went into my fuel tank. I tried to look into the tank via a mirror first and eventually bought an usb borescope camera to look into the tank but I could not spot even one piece of the rubber. The usb cable is hard to control so I'm sure have not scanned through the whole tank either. The missing rubber part is about 1/4 inch (see attached photo comparisons with a dime and a quarter).

Any suggestions on how to get such items out of my fuel tank? It looks like there's not enough space to remove the tank without removing the upper Ultimate wings?
