Bjorn in Cobble installs veg oil systems. He is very knowledgeable and has installed both Elsbett and Plantdrive systems. When I was there trouble shooting my system he showed me the Elsbett system he was installing in a Mercedes. It was the one tank sytem. He commented that he liked the Plantdrive much more, for quality of materials to ease of installation. But that is just one man's opinion.
I really liked the idea of Elsbett at first as there was a specific design for the Delica but the price plus shipping plus custom brokerage etc put the cost out of my range. And i sounded like the install would require many more hours and more knowledge of engine. ie injectors and special tools.
I have enough trouble installing a system that essentially involved just tee into exsisting lines

. But that was what I was comfortable with.
