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.
