Re: Heater hose connections

Mark, please refer back to posting #11 above. The supply and return hoses for the underseat unit follow a general routing from the heater-defroster unit on the passenger side, not the driver side. These are long runs, especially the return hose to the water pump. I don't have the car at home now to check exactly how they are routed, but would think it would be easy to figure out. I don't recall seeing any brackets for the hoses on my Custom, but not sure about this. Just be sure the hoses are not placed where they can be pinched, burned, or chafed.

Actually, unless you are planning on driving the car in very cold weather, the underseat unit is probably best left unconnected. Most of the benefit is derived from the heater-defroster unit under the dash as it is the first to get warm water from the engine.

Edit: Howard is quicker on the keyboard than I and his photos show hose routing like my 47 Custom including the brackets.
