Good morning Greg , I have some pictures being developed now that will help you , the very first filling stations were where the old delivery stables were , tran-tank cars brought fuel in to that point , the tanks at the stables were high on a mound and gravity fad to were they could put it in the carts , if there was an other depot at the other end of town they transported it buy horse an wagon , they also used horse and wagon to haul oil from the wells ponds to the refineries un til they came up with a pumping system that would pump crude oil which was very thick , but i have pictures of some of this , hope this helps you for now ,
