Ed is correct...most small portables have the fuel tank above the carb. and use gravity to feed the carb. Facet makes low pressure pumps that are 12 volt and that is the types that are used on Onan's and others that pull fuel from another tank. Those pumps are readily available at many auto parts stores and other suppliers. Pressure is about 2-4 lbs. You have to have it hooked to the battery and only running when the generator is running and you will need some sort of battery charging to keep the battery from going down. RV type units like an Onan have this all included in the design......
