Public Utilities Code section 99509
(a)
Notwithstanding Section 99505, any person required to pay a license tax under Section 7351 of the Revenue and Taxation Code shall also collect the tax imposed under this chapter from any person to whom he sells or distributes motor vehicle fuel and shall pay such tax also for all such fuel that he uses.(b)
Subdivision (a) of this section shall become operative only if a ruling of a federal agency becomes effective which precludes the tax imposed under this chapter on motor vehicle fuel from being included in the price charged by distributors to retailers or other persons, or precludes the increment of any price paid to the distributors that represents the tax imposed from being included in the price charged by retailers or other persons upon resale of the motor vehicle fuel, and, in such case, this subdivision shall become operative at the same time as such ruling becomes effective.
