[DeTomaso] clutch master cylinder ptroblem

[boyd casey]

Can anyone t ell me the size of the fitting that holdst the copper clutch
line in the clutch master cylinder ? ( and where to get one) or is there a
braidedstainless steel line and AN fitting I can use instead of the copper
line and brass fitting. I seem to be leaking air from that location. I have
replaced the clutch master twice and still can't get it to build up any
pressure. I pump it and when I bleed it air comes out and the pressure never
gets any greater. There is air released every time I bleed it.
