Section 43835 Of Article 3. Fuel And Fuel Tanks From California Health And Safety Code >> Division 26. >> Part 5. >> Chapter 4. >> Article 3.

. (a) The state board shall, by March 1, 1976, adopt specifications for the fill pipes and openings of motor vehicle fuel tanks to ensure that the size, design, and location of the fill pipe and opening permit adequate access to and interfacing with gasoline-dispensing nozzles for the purpose of vapor control.
  (b) No new 1977 or later model year gasoline-powered motor vehicle may be sold, offered for sale, or registered in this state unless such vehicle is in compliance with the specifications adopted by the state board pursuant to subdivision (a). The state board may exempt from such specifications those classifications of motor vehicles for which the state board determines the specifications are technologically infeasible. The state board also may waive the provisions of this subdivision for any 1977 model year gasoline-powered motor vehicle, provided that the state board makes a finding, based upon evidence presented by the manufacturer of such vehicle, that inadequate lead time exists for any required vehicle redesign. The state board may make such waiver applicable only to specified body styles of such a vehicle.
