## Abstract

A method of delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. A first tank is filled with the fluid and is fluidically coupled to a second tank which may be pressurized by a compressor. The second tank is fluidically coupled to a manifold which is in turn coupled to a fluid transporting mechanism. The fluid transporting mechanism is fluidically coupled to a hydraulic connector of a fill cap which is coupled to an opening of the fluid tank. The fluid is directed from the first tank to the second tank, the manifold, the fluid transporting mechanism, the hydraulic connector and into the fluid tank through an outlet of a probe of the fill cap.
