RF97 fuel cells

I am having some problems with my fuel cell and was thinking someone here may be able to help me sort out some things. In my RF97 I noticed at homestead when I checked my fuel with the dowel dipstick I use, some foam material was on the stick. so I figured the foam must be breaking down. also at top speed full throttle it fell flat and stumbled as if it wasn't getting enough fuel. is there a screen that may be restricting flow? maybe. anyway I order fuel cell foam in a large block to cut down and replace after cleaning up the inside of the cell. as I go to remove the cell I find it is leaking into the bottom of the floorpan and there doesn't seem to be a removable panel to access the inside unless it is in the back bottom corner. anyone know what the configuration of that cell is? also if I have to replace the whole cell where can I get one as it seems this is not a common size but rather a custom cell made just for this car?
