A system for transferring fluid from a filling reservoir to a receiving tank. The system includes a fluid transfer line for conveying fluid from the filling reservoir outlet to the receiving tank inlet, and couplings for selectively connecting the fluid transfer line to a filling reservoir outlet and a receiving tank inlet. The system further includes a vapor return line for conveying vapor from a receiving tank vent to a filling reservoir inlet to simultaneously prevent pressure from building in the tank and a vacuum from developing in the reservoir as fluid is transferred from the reservoir to the tank, and couplings for selectively connecting the vapor return line to the filling reservoir inlet and the receiving tank vent. In addition, the system includes a portable platform adapted for movement to a position near the filling reservoir and the receiving tank, and a pump mounted on the platform for selectively inducing fluid to travel through the fluid transfer line from the filling reservoir to the receiving tank when the reservoir outlet valve and the tank inlet valve are open. The system also includes a compressed gas source in communication with the fluid transfer line for blowing gas through the line to remove residual fluid from the line to prevent the escape of residual fluid and associated odor from the line when the fluid transfer line couplings are uncoupled from the filling reservoir outlet and the receiving tank inlet.

[ What is claimed is:] [1.] A method for transferring fluid from a filling reservoir to a receiving tank, the filling reservoir including an outlet for the discharge of fluid from the reservoir, an outlet valve for selectively controlling fluid flow through the outlet, and an inlet for permitting vapor to enter the reservoir to prevent a vacuum from developing in the reservoir when fluid is discharged from the reservoir through the outlet, the receiving tank including an inlet for permitting fluid to enter the tank, an inlet valve for selectively controlling fluid flow through the inlet of the receiving tank, and a vent for permitting vapor to escape from the tank to prevent pressure from building in the tank when fluid enters the tank through the inlet thereof, the method comprising the steps of:connecting a fluid transfer line to the filling reservoir outlet and to the receiving tank inlet;connecting a vapor return line to the filling reservoir inlet and to the receiving tank vent;opening the reservoir outlet valve and tank inlet valve after the fluid transfer line and vapor return line are connected;conveying fluid through the fluid transfer line from the filling reservoir to the receiving tank when the reservoir outlet and tank inlet valves are open;blowing gas through the fluid transfer line to remove residual fluid from the fluid transfer line;closing the reservoir outlet valve and the tank inlet valve to prevent fluid flow through the filling reservoir outlet and the receiving tank inlet; anddisconnecting the fluid transfer line and the vapor return line from the filling reservoir and the receiving tank after residual fluid is blown out of the fluid transfer line and after the reservoir outlet and tank inlet valves are closed. [7.] A system for transferring fluid from a filling reservoir to a receiving tank, the filling reservoir including an outlet for the discharge of fluid from the reservoir, an outlet valve for selectively controlling fluid flow through the outlet, and an inlet for permitting vapor to enter the reservoir to prevent a vacuum from developing in the reservoir when fluid is discharged from the reservoir through the outlet, the receiving tank including an inlet for permitting fluid to enter the tank, an inlet valve for selectively controlling fluid flow through the inlet of the receiving tank, and a vent for permitting vapor to escape from the tank to prevent pressure from building in the tank when fluid enters the tank through the inlet thereof, the system comprising:a fluid transfer line for conveying fluid from the outlet of the filling reservoir to the inlet of the receiving tank, and couplings for selectively connecting the fluid transfer line to the filling reservoir outlet and the receiving tank inlet;a vapor return line for conveying vapor from the vent of the receiving tank to the inlet of the filling reservoir to simultaneously prevent pressure from building in the tank and a vacuum from developing in the reservoir as fluid is transferred from the reservoir to the tank, and couplings for selectively connecting the vapor return line to the filling reservoir inlet and the receiving tank vent;a portable platform adapted for movement to a position near the filling reservoir and the receiving tank;a pump mounted on the platform for selectively inducing fluid to travel through the fluid transfer line from the filling reservoir to the receiving tank when the reservoir outlet valve and the tank inlet valve are open; anda compressed gas source in communication with the fluid transfer line for blowing gas through the line to remove residual fluid from the line thereby to prevent the escape of residual fluid and associated odor from the line when the fluid transfer line couplings are uncoupled from the filling reservoir and the receiving tank.
