I would be surprised if they were the same. The usual pump on a Super C was a PESCO pump with some having Cessna pumps. At least the Cessna is what is offered now. I replaced one a few years ago and it was quite expensive. There was another pump made by Thompson that was also used, but I don't think it is available anymore.
I would have thought that the French Super FC (at least the gas version) would have the same pump mounting bolt patterns. I also think the French would have used either a French or German made hydraulic pump from a local supplier. So in concluding, it is possible an American made pump might fit at least in the gas version. For the diesel version, it is anybody's guess as to what would fit.
