When you are about to start making biodiesel, make sure that you have the right Biodiesel Manufacturing Equipment.  Not having the right equipment and the right ingredients will not take you very far.  I have always believed in the saying, "Do it right the first time" because there really is no any excuse for not following what has been explicitly said unless you really want to fail.  It is not really that hard to find as there are kits which are available on the web.  You can buy it anytime.  Plus the fact that there is help online and there are tutorials that can be found on the web when making biodiesel.
