They all break,steel cracks,nylon gets old,hard,and breaks,copper breaks,wires break or get chewed up by mice senders go bad so the only real bulletproof option is screw a mechanical gauge,directly into the galley port,you can't see it but nothing will break.Use whatever tubingbyou want,use common sense routing it,hard line put a coil in it for movement,when it breaks repair it. Same as everything else on these trucks when the brakes go out change them when the gas tank rusts out,change it. Do you see a pattern?
