The warped bulk standard model has been studied in the Randall-Sundrum background on S1/Z2×Z2′ interval with the bulk gauge symmetry SU(3)×SU(2)L×SU(2)R×U(1)B-L. With the assumption of no large cancellation between the fermion flavor mixing matrices, we present a simple analytic method to determine the bulk masses of standard model fermions in the almost universal bulk Yukawa coupling model. We also predict Ue3 element of MNS matrix to be near the experimental upper bound when the neutrino masses are of Dirac type.
