[SEL] clogged pipe help

[Germoamer at aol.com]

I need some list help to unclog a pipe in a gas tank.  See picture to better 
understand.

I am working on the gas heater for the soldering irons.  The tank was full of 
dried junk and finally go it all out by shaking rocks inside for quite some 
time.  However, the discharge pipe in also clogged.  I have removed the cut off 
valve (to the right of tank).  The pipe is welded to the tank and is radiused 
inside down to the bottom of the tank.  Thankfully this was done rather than 
a right angle as it makes it easier to push something down it.  I have tried 
forcing air, and a number of wires, braided wire on the end of a drill, etc., 
all to no avail.  The pipe must be full of dried junk.  I now have it standing 
upright with carb cleaner soaking in the pipe.  Maybe I need to contact Mr. 
Roto-Roter!

Does anyone have any ideas how to unclog the pipe?  It is 1/4 inch steel.

Thanks,
