Installed Lovecraft Heat Exchanger

Installing the heat exchanger from Lovecraft Biofuels proved to be extremely simple.  The heat exchanger replaces the standard fuel filter that comes with the Mercedes 300 series car. It doesn't filter the fuel, rather, it uses engine coolant/water to heat the fuel. 

Here are the steps required to install the heat exchanger:

1. Drain the coolant/water from the radiator
2. Disconnect the coolant line where it goes into the heater/filter (mine is a Davco 234)
3. Connect that coolant line to one of the fittings on the new heat exchanger (I shortened the hose by 8 inches or so)
4. Use another piece of coolant hose to connect the other fitting on the heat exchanger with the heater/filter
5. Replace the radiator drain plug and refill the coolant/water

That's it.
