There is no port and if an electric fuel pump is available you could just pump it into containers. Using a fuel pump connected to the 3/8″ fuel line that goes to the engine from the valving. You can connect the fuel pump hose at the valve and remove it with the pump. The next option is to simply siphon the fuel through the fill neck, using a hose and stick to support the onhose extending into the tank. There is an anti siphon valve on the pickp that will not allow the siphon to function on the pickup line. Obviously 3 year old fuel has to be removed and we are suspect you will see phase separation and moisture in the fuel.
