97 XJ brake lines.

I've done a lot off brake tubing but never a Cherokee. Brake line running along the the inside of the frame rail is toast...and so is the other small "vent" line running to the fuel tank....
Is this a metric brake line? I notice it fastens to the rear brake hose with a female fitting rather than the usual male fitting. Or is it 3/16 tubing with different fittings? Thanks

Should be standard. Most parts stores carry straight brake line and you bend it to fit. Should be able to look up by application.
