Hi all, anyone know the workings of the fuel preheater unit? it seems to have a vacuum line run from top to bottom, and tee off to go somewhere. mine is just hanging, going nowhere. Truck runs great, but that line is wierd.

Also, I'm hooking up a secondary fuel system, heated, for veg oil. I'm thinking it's great to have the pre heating, could prob run 50/50 perfect. I have a heat exchanger to include in my system, but am wondering the specs on the stock heater unit. Anyone?

Love this truck.

Thanks in advance!

Jesse
