Portable pump and fuel containment system

A portable pump and fuel containment system comprising:

• a portable base assembly comprising:
• a lower support having an upper surface and a lower surface;
• and
• a plurality of wheels coupled to the lower surface of the lower support;
• a container on the upper surface of the lower support, the container defining an interior volume, an inlet port in fluid communication with the interior volume, and an outlet port in fluid communication with the interior volume;
• and
• a liquid transfer assembly coupled to the portable base assembly, the liquid transfer assembly comprising:
• a pump comprising an inlet, an outlet, and a motor;
• a three-way control valve comprising a first inlet, an outlet, a second inlet, a valve, and a lever coupled to the valve, wherein the lever is movable between a first position in which the valve places the first inlet in fluid communication with the outlet, and a second position in which the valve places the second inlet in fluid communication with the outlet;
• a flexible transfer line comprising a first transfer line segment and a second transfer line segment, the first transfer line segment being coupled to the first inlet of the three-way control valve and the second transfer line segment extending from the outlet port of the container to the second inlet of the three-way control valve;
• and
• a flexible return line having a first end coupled to the outlet of the pump and a second end detachably coupled to the inlet port of the container,
• wherein the outlet of the three-way control valve is connected to the inlet of the pump,
• wherein, when the pump is activated and the lever is in the first position, the pump pumps fluid through the first transfer line segment and the flexible return line and into the interior volume of the container through the inlet port, and
• wherein, when the pump is activated, the lever is in the second position, and the second end of the flexible return line is detached from the inlet port, the pump pumps the fluid in the interior volume of the container out through the second transfer line segment and the flexible return line.
