We investigate correlated electronic transport in single-walled carbon nanotubes with two intramolecular tunneling barriers. We suggest that below a characteristic temperature the long range nature of the Coulomb interaction becomes crucial to determine the temperature dependence of the maximum G_max of the conductance peak. Correlated sequential tunneling dominates transport yielding the power-law G_max ~ T^{\alpha_{end-end}-1}, typical for tunneling between the ends of two Luttinger liquids. Our predictions are in agreement with recent measurements.
