nmtrains posted:BF166,Sorry for your dilemma! If I'm reading you right reducing tube size would create a "bottle neck/pressure problem"-I would think-perhaps bursting tube at this point(when in prime mode} We'll see what Lionel has to say! Hope this isn't an "Archilles heel" in this product though.
Good point,......but Lionels molded insert also narrows the original tube so it fits into the pump.....what I did simulates it.....nevertheless.....I will see if Lionel will send me out a new tube.
