I also got mine from HPSI, I picked up 70 feet of the 3mm. Why 70 feet, you ask? Because the 7 colors they offer, in 10 foot minimums ($1.20/ft), match the color coding stripes on the original hoses, if you use silver/grey for the white striped hose. I figured this would be appreciated in the future as I traced the stunning number of vacuum circuits on the 3.5, and figure Mitsu techs would figure it out pretty quick if they were ever to work on it again. I am very impressed with their hose by the way.
