I had a fuel hose on my 4020 LP tractor to break. Went to the JD dealer and they wanted $42 for the 10" hose. Said no thanks and went to my LPG dealer and bought 4' of hose and two reusable hose ends and made my own hose for $23. As far as the regulater goes, I would definately place it on the tank and just use a longer hose to connect the grill. If anything happens then you only hace a couples ounces of pressure to deal with instead of upwards to 250#.
