I'm getting ready to build a cabin out in the sticks, and have a diesel generator for running my tools that I'd like to run on veg oil. I have a good clean source of filtered fryer grease, but don't know how to proceed. Does anyone have experience or advice? I know I need to build an external heated tank to hold the oil, and some way to pipe it into the engine with a switch valve, but I'm not sure what to use and how to build it. Thanks for any help!
