Hi all. I’m sorry that this thread doesn’t come with pictures but I’m on a plane to NZ for two weeks and didn’t have time to take any. I have two Aladdin suitcase stoves currently. One has a removable pump tube and the other has the pump tube as part of the tank. Any idea which is the older model? From memory the one without the removable pump tube had the lines for the burners coming out either side of the tank. Any info would be greatly appreciated. Both work really well, great stoves!
