My 1982 air cooled Westy has the factory installed auxillary heater.  When I turn it on the combustion blower and the fresh air fan (the fan that takes in fresh air from beneath the bench and pushes it through the heater and into the bus) starts.  The fuel pump does not start.  I bench tested the fuel pump with a 12 V battery and confirmed that it does work. It seems that the pump is not getting the signal to do its thing.  As best I can tell this signal is controlled by a set of points in the combustion blower fan.  I have pulled the fan, but have not been able to locate these points.  Anyone have any experience with this?
