Good Morning, We have a 550 gallon diesel fuel tank that we would like to install outside our manufacturing facility in close proximity to an interior emergency generator as the fuel source for the generator. We can get this located 8' horizontally from any opening to the facility. What is the minimum distance we can place the tank to the building? Where can I find all the information about this and who can I find to install it? I have talked with tank companies and they say they build them, but don't know the specifics about installation.
