Okay... I know this is not a big deal. I've seen it in other people's frunks. And this could possibly be the stupid question of the century. But, it's driving me crazy not knowing. I looked it up in the BGB. The only reference I can find is the water valve which it is connected too. So, maybe this is for draining?
Here's a pic... see the coiled up piece of clear hose. Notice there is more than one piece in there? What the !@#$ is that for?
Here's a close-up... it's all kinked up. Look at it... it's just taunting me. Damn you hose!
Please help me sleep at night... I need help!
