each rear has its own line, if you look in the rear d/s wheel well you'll see one line to the d/s rear, then the other one goes and clips into the rear sub frame where theres a dumb coil of line on each side. in the frame is where mine blew out.
i cut the line in the open of the d/s wheel well, then ran a new line from it to the other side laying th enew line behind the gas tank.
drivers side, left side is the left rear brake hard line to rear hose.
compression fitting is the new line. cut in the open area to work on it.
new line bent around the back of the gas tank.
pass rear, i cut the old line a few inches from the block for the hose.
judging by how far back i had to go to find these pics, its a 3 year old repair now. compression fittings are holding just fine still.
