I was fed up with the funnel.
Every time I filled up with biodiesel before, it’s been an awkward dance with a dripping funnel, best executed with two people, at worst balanced with a couple of cold fingers and at least one fatiguing arm muscle balancing the jug and waiting for it ever so slowly to empty.
My DIY device doesn’t have a breather, but the containers the biodiesel comes in are flexible, so the sides suck in and they still empty into the tank in a few seconds. Easy and expeditious.
Now running bio is just that much more pleasant, and the semi-virtuous mixed feelings about driving continue.
