WARNING purchasing of gasoline from non authorized vendors

There are places way out in the boodoks that do not have a gas station and fuel is sold from houses or a tlapaleria or the corner store they are known to PEMEX, the guachicoleros are close to citys where the pipe lines run, I am trying to find out where they operate other than the state of Puebla, so that the RVing comunity knows.
