The first 3 photos are of a field trip I took to Shawsheen Valley Technical High School in Billerica, MA to show the Jetta to John Havens (diesel mechanic teacher) and his class. There web site is here: Shawsheen Shop Program. The last 3 photos show how to modify the buckets to have spigots for use in veggie oil filtering.
I made up some more bucket /spigots combos for filtering veg oil
These are the finished units ready for use
