one or both of these are severed, do they go to the fuel tank? i wasn't sure if they were the vapor return lines or e-brake or drum brake lines... The drum brakes are making noise, but work, so i'm gonna rebuild them, the e-brake works, but not well, never did. so i'm down to fuel, the car still runs, drives and nothing leaks out of these lines. Is it the fuel vapor return, this would make sense, given location and direction. I'm not going to take anything big apart, but they are now routed under my sub-frame connectors, I have the carbon canister blocked off and the lines and plug out, so I'm not sure this matters, but I wanted to be sure what these 2 lines were. also, drum brakes, how do you check to see if the drum needs to be replaced?
