I had two very bad bulges on either side of my fiberglass shell. They were deep also! I was sitting there wondering HOW I was going to fix it, as I did not want to dig out a large section of fill. So.. I used a shop-vac! With several extensions and a narrow nozzle I was able to slowly move downward and across about a 5 foot area behind the wall. The wall slowly went back into place as I went along.
