G4226A Autosampler - leaking needle assembly-loop capillary

I have replaced the needle assembly on a G4226A Autosampler.  There is now a leak from the fitting of the loop capillary.  I have tightened the fitting of the loop capillary as tight as I can, without risking damage.  After 6-7 attempts, with the same new needle assembly, it is still leaking.  It is a small leak that isn't affecting the system pressure.  Over time, the liquid will reach the leak detector.
