Good stuff. I also am filling a sac between the engine compartment and seat. So Iíll follow the path you described. I have a question though about the route through the ski locker. I looked at where they ran the battery cables also, but since I am filling a 375lb sac in the ski locker I thought with the hoses running through there, there might be some restrictions when the sac fills up. My sac takes up the whole locker when Iíve filled it manually. Have you had any issues?
