    Just think of the AN number as being the first diget of a fraction and 16 being the second... ie: -6 = 6/16ths or 3/8"

    The flares are 37 degrees instead of a standard 45.

    yep -4 is basically 4/16s. Its not really the size but the amount the fitting flows in comparison to a normal fitting of the size. -4 Flows like a 4/16" line would. Had a whole lecture on fittings in class today :rolleyes:

    -4 seems VERY small for fuel line. I have -4 brake lines for the S10.
