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

I don't exactly understand your question, did you run the metal tube too far into the tank or is the clunkline very stiff?

i dont think i ran the metal line too far in the tank. as far as the line being stiff, i forget the diameter of it but its the larger size line. its feeding a moki 2.10
