I always run an electric pump and dont waste my time with a mechanical pump. Yes carry a spare if you feel better but my sons Dart has been on the road since 1997 and is still using the same red Holley pump. In hot weather you wont have to worry about vapor lock or fuel boiling with an electric and there is no way a mechanical pump will work as good as an electric pump and if you plan to race you need it that much more.
