This is great! Nice scale, I used to make my own biodiesel and also run veg oil sometimes. Veg oil concerned me enough to limit its use to long distance high speed/load driving where things stayed good and hot, and run on Dino for a long time before shutting down….
Biodiesel was great, but I was living in an apartment so made batches using large stock pots. It was good for adding lubricity and cleaning to the fuel system.
I probably could make a system like yours, alas, these days I don’t have the time or energy to get the veg oil….
nice work! I look forward to seeing more!
