In this paper we characterize √(2)-1-uniform J-Parseval fusion frames in a Krein space \mathbbK. We provide a few results regarding construction of new J-tight fusion frame from given J-tight fusion frames. We also characterize any uniformly J-definite subspace of a Krein space \mathbbK in terms of a J-fusion frame inequality. Finally we generalize the fundamental identity of frames in Krein space J-fusion frame setting.
