I'm posting this here because I plan on running WVO sometime in the future. I just bought a 2004.5 Ram 2500. The first thing I want to do is put on a Fass fuel system. I haven't bought a book but I know there is a fuel pump on the side of the engine. If I install a Fass does it take the place of the fuel pump in the engine compartment and can I run WVO through the Fass or should I setup a seperate filter system independent of the main fuel supply?

 

I know this is way old, but I'll try anyways.

You should NEVER run WVO through your factory fuel system. The correct way of running WVO is a heated, two-tank design. It is basically a complete secondary fuel system from tank to pump. It only shares injectors and in the case of the commonrail motors, it will share the CP3.

 

Thanks for information. I looked further into it and discovered the same thing. I decided to try out biodiesel and made a couple of one liter test batches already. My idea on the biodiesel is no extra tank and pump and I might be able to use it in my home oil burner for heat.

 

Yes that's always another option.

The main reasons I didn't go bio for myself:

Bio is better if you're running more than 1 vehicle on it
Bio is not going to work in my cold climate during the winter months
I didn't want to have caustic chemicals in a house I'm renting

So it just boils down to what is right for you I guess. For me, just the fact of being able to burn WVO all year round, when I couldn't do that with bio was enough to push me to the WVO thing, but like I said it boils down to what saves you the most money!
