fp - can you post a pic of your filtering system. I am trying to picture it and envision something to the effect of pumping the "raw" oil out of a 55 gallon drum through the filter system into a clean 55 gallon drum that you then put in your "alternative" fuel tank on the car. Do you have to keep it "hot" in your storage container to keep it "flowable"? Is that the reason you have to keep the container in the car hot along with the lines? Do you use solenoid valves to switch between tanks in the car?
Thanks
