ok guys this is a really stupid question so please bear with me.
I just recently got into 1.20 and larger type planes and im having a problem getting the clunk to goto the stopper end on the tank when the stopper is pointing to the floor. I have tried using the heavy clunks but unless i shake the tank it will not go. Is it neccesary for the line to go all the way to the stopper or what. Thanks in advance
