Exposed Tanks / Piping
Sheesh, I did not say that the Advantage Series is the only type of pump on the market, I merely presented that as an example cuz by now I forget what the argument is about (a) three hose vs one hose dispensing station (b) if the aboveground dispensing station has a pump (c) the three-way valve.
A - There are both types.
B - It does.
C - There are two Shell stations within four miles of my home that have had their tanks exposed within the past three months. Because I am the curious sort, I stopped by during construction activity. From each underground tank, there were two lines going to each aboveground dispensinf station - delivery and return. I do not have access to the construction drawings, so you will just have to believe me. Or not, whichever you select.
