Probably one of the tank module seals has failed. Start with the offside as that one is the first usually to be disturbed as the ITP sits on that side. Lift the rear seat base, and then the cover over the module and then unscrew the retaining ring. Check the seal is fitted the correct way round and that it is fitted into the tank before the module is lowered in. If you fit the seal to the module and then fit them into the tank that can lead to a leak.
