I figured out the gas tank. I purchased a 6 gallon gas tank for a boat and the fuel line with priming bulb and a couple of fittings for the fuel line. I drilled a ?" hole in the pump gas cap and screwed the fitting into the hole. Then connected the new gas tank to the one on the pump. I then took silicone and sealed the vent on the gas cap. I placed the new tank at roughly the same height as the pump's gas tank and it sucks the gas right out of the new tank into the motor. Worked like a charm. Now I can run it 7-8 hours without filling up the tank. I will take some pictures tomorrow morning.
