A fuel supply system for a portable engine driven device is provided which comprises two fuel tanks that are spaced apart from each other. The two fuel tanks are connected in fluid communication by a first conduit that is connected to each fuel tank at a bottom portion thereof and at a region of that bottom portion which is closest to the other fuel tank. A fluid pumping means is provided and connected in fluid communication with each of the two fuel tanks for pumping a liquid from the two fuel tanks toward a device which requires the use of the fluid. For example, if the liquid in the tanks is a liquid fuel, it can be pumped for use by an internal combustion engine. In addition, the internal combustion engine can be connected in torque transmitting relation with a compressor such as in a portable engine driven compressor apparatus.
