It's not the scratch I'm worrying about. it's the brake solenoid, whenever you press your brake, that's when intake tube is hitting brack solenoid. if that breaks then that's big problem.ards said:In order to prevent scratching, I just wrapped it with some rubber to make it as a cushion from that brake solenoid. And keeping an eye on it, it works fine for me. No more scratches and with just one bracket connected to the spare bolt near the battery.
