Its not always the tank. If you dont have enough presure coming from the exhaust system it will act like your out of fuel. Loose header,bad gasket, cracked coupler seal,plugged presure nipple on pipe. Just make sure your presureizing the fuel tank. When the level in the tank drops below the carb level fuel doesn't flow very good without some help.
