Just leave it be. Scarey thought, but probably not the only "foreign" matter in there, and will be the least of it........The fuel pickup will NEVER be able to suck that puppy up off the floor of the tank.
As far as what the hose got hung up on in the first place, however, COULD have been the pickup tube or sending unit floats, and THAT might be a concern requiring removal (Or cutting a big hole in the hull) if your yanking on the hose damaged them.
