  In this paper we characterize $\sqrt{2}$-1-uniform $J$-Parseval fusion frames
in a Krein space $\mathbb{K}$. 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 $\mathbb{K}$
in terms of a $J$-fusion frame inequality. Finally we generalize the
fundamental identity of frames in Krein space $J$-fusion frame setting.
