JC Whitney was where I got mine. I would highly recommend the squirrel-cage
type (cost $89) over the bilge blower type ($69). The S-c type is nearly
silent, and blows a heap more air than the bilge blower type. Further, I
wouldn't use paper tubing. Re-use the stock tubing, which has a little
insulation, but surround it with Hart & Cooley R-6 or R-4.3 insulated Mylar
ducting. The 4" ID version fits great, and will make a dramatic difference
in the temperature of your heat. Costs about $14 for a 25-foot box.

Instructions follow: (posted once before, but here it is again for your
conveyance. :)

Subject:        Heater booster sources?

I've borrowed the ramps and have started re-vamping the heater system of my
'80 westy and I need to find a source for the blowers (inline) to assist
the
fan and the paper tubing in betwixt.  TIA,
