## Abstract

In a method and system for delivering fluid to a fluid consuming asset having a fluid tank, an inlet of a manifold is fluidically coupled to a tank and an outlet of the manifold is coupled to a spigot. A pressure relief valve is disposed between the tank and the manifold to facilitate fluid flow back to the tank through a recirculation inlet when the back-pressure in the system reaches a threshold value. A first distal end of a fluid transporting mechanism is coupled to the spigot and a second distal end thereof is coupled to a hydraulic connector of a fill cap having a connection plate coupled to the fluid tank of the fluid consuming asset. The fill cap further comprises a probe and fluid flows from the first tank to the second tank, through the manifold and the hydraulic connector, through the probe and into the fluid tank of the fluid consuming asset.

a manifold having a first inlet and one or more outlets, wherein the first inlet of the manifold is fluidically coupled to an outlet of the other tank through a fluid coupling, and wherein the first fluid flows from the other tank into the manifold through the first inlet;
a first pressure relief valve disposed on the fluid coupling between the outlet of the other tank and the first inlet of the manifold,
wherein the first pressure relief valve is set at a first predetermined pressure threshold,
wherein the first pressure relief valve opens when the back-pressure in the fluid coupling exceeds the first predetermined pressure threshold, and
wherein the first fluid is directed back to the other tank through a first re-circulation inlet when the first pressure relief valve opens;
a spigot fluidically coupled to one of the one or more outlets of the manifold,
wherein a first distal end of the spigot is fluidically coupled to the one of the one or more outlets of the manifold and a second distal end of the spigot is fluidically coupled to a fluid transporting mechanism, and
wherein the fluid transporting mechanism comprises a first distal end fluidically coupled to the second distal end of the spigot and a second distal end; and
a fill cap, wherein the fill cap comprises:
a connection plate, wherein the connection plate is coupled to an opening of the fluid tank of the fluid consuming asset;
a hydraulic connector fluidically coupled to the second distal end of the fluid transporting mechanism;
a probe disposed within the fluid tank of the fluid consuming asset,
wherein the probe comprises an inlet at a first distal end coupled to the connection plate and an outlet at a second distal end within the fluid tank;
wherein the inlet of the probe is fluidically coupled to the hydraulic connector and wherein the first fluid flows from the fluid transporting mechanism, through the hydraulic connector and into the probe through the probe inlet, and
wherein the first fluid flows into the fluid tank of the fluid consuming asset through the outlet of the probe;
a second pressure relief valve fluidically coupled to the other tank through a second recirculation inlet,
wherein the second pressure relief valve is disposed on the manifold,
wherein the second pressure relief valve is set at a second predetermined pressure threshold,
wherein the second pressure relief valve opens when the back-pressure in the manifold exceeds the second predetermined pressure threshold, and
wherein the first fluid is directed back to the other tank through the second re-circulation inlet when the second pressure relief valve opens.
