Not quite sure how to go about removing the fiberglass that covers 1/2 of the sending unit's screws. Any help would be appreciated. I've thought of 4" Hole saw, Saber Saw, Dremel tool?. Thanks. :)

I had great success with one of those oscillating tools and a plunge cutter blade. I cut out a rectangle about 2" by 4" with very clean cut lines. I plan to replace it (some day) using a sealant like 4200.
