I know the OP was about not using pumps, but I tried various methods and ended up with a Dubro Kwik Fill Hand Crank Fuel Pump. It is a fantastic product, and the model 911 comes with the fuel tank fittings as well, compatible with glow fuel and gasoline. Having been involved in a gas fire caused by electrical equipment, I'll never use an electric pump with a gasser. You don't know where the fumes will go, but if there is a spark, it is "ka-whoosh" time.
