Was thinking about it and I guess the best and easiest way would be the just put a valve in just before the heat exchanger. The diesel then would come out of the tank, to the pump, filter, and heat exchanger, but not be heated. Simple, but only problem would be having to crawl under the truck every time I want to do that.
