Corny keg gas in - tube?

[johnmac]

If the keg is filled to nearly full, the gas - in tube will be in the beer. The tube appears to be longer than it needs to be.

Before I cut 1/2" off the tube, can anyone think of a reason why I shouldn't do that?

Thanks for the warning! I think I'll cut off flush with the top of the keg.
