The gray spiral wrapping around the cable harness to my engine is cracking and breaking in a couple of spots. See pic . What is this called and is there something better to use. I assume it's to keep cables neat and possibly prevent sun UV rays from drying up the cables !! .. By the way that clear filter in pic provides a way to visually monitor fuel flow, I have a water separator/filter setup installed inside to actually do the heavy duty filtering.
