I'm about 75% complete my stearman build, this is my third plane, but first arf build, and have one quick question about the fuel tank setup.  I am using the stock tank, with du-bro neoprene fuel line on my clunk, my question is, does the clunk have to be able to make it to the front of the tank as well?  The clunk only moves about the rear of the tank, the line doesn't bend enough for the clunk to reach the front of the tank, should it?
