Are they the 1/8" lines shown on the left in my photo?  I got 1/8" tubing from a Parker Store when passing through Grand Rapids, MI.  For the 90º fittings, I put a brass Street Ell in and then straight 1/8" compression fitting into the Street Ell.  The compression fitting came from Ace Hardware, I believe.

Could be. My photo is a CU. I can get a wider shot. Tubing says Parker Parflex FFT-2A 1/6.
