  In this paper, the generalized fractional operators involving Appell's
function $F_3$ in the kernel due to Marichev-Saigo-Maeda are applied to the
generalized $K$-Wright function. These fractional operators when applied to
power multipliers of the generalized $K$-Wright function ${}_{p}\Psi^k_q$
yields a higher ordered generalized $K$-Wright function, namely,
${}_{p+3}\Psi^k_{q+3}$. The Caputo-type modification of Marichev-Saigo-Maeda
fractional differentiation is introduced and the corresponding assertions for
Saigo and Erd\'elyi-Kober fractional operators are also presented. The results
derived in this paper generalize several recent results in the theory of
special functions.
