Cant put gas in new tank. Help

I'm not all that familiar with the specific parts over the years, nor imperfections in 'repops.' Seems to me the most probable situation is that the filler tube, for some reason, extends to far into the tank.

So far as a can, only thing I could suggest is to ring a lot longer nozzle. I could envision a situation where gas is cascading down the filler tube, forming a "wall of gas" at the same time as air is trying to get OUT. If you had a longer nozzle, it might be that you'd then have enough room for this all to break up, so to speak, before being forced that far up.
