My 76 C-10 cracked the steel oil pressure line at the firewall grommet. I've searched for the 1/8 male compression fittings to replace this and have come up empty-handed. I have a Sun Pro kit that has every kind of fitting except the right one. Most parts stores give me a blank stare, though Auto Zone dug up a couple of female unions that I could use to cobble things together. Does anybody have a source for these fittings, or a decent workaround?
Best regards, Ralph in NH
