I had an 1988 Ram 50 2wd that the line sprung a leak after I fixed the fuel line. Ended up replacing the line from the master all the way back to the axle, the lines on the axle, and both wheel cylinders. With that year, the line goes in the top of the wheel cylinder, then goes out the bottom to the other wheel cylinder - both cylinders bleed from the pass side. If you haven't changed the fuel line yet, expect to change that too once you disturb it to fix the brake line.
