Conversion Factors:= 1 "cubie" = 35KG of vegetable oil Soybean and Canola Oil weighs 7.6 pounds per gallon (source) #2 Diesel fuel weighs 7.2 pounds per gallon (ibid) 1 cubie = 4.6 gallons Filtration: Primary filter: oil filter from a 1982 Volvo 240 w/ 6 cyl Diesel motor Purolator L17019 Secondary filter: fuel filter from Izusu earth mover (generally only available at napa) Napa part # 3389 Purolator # F54509 (?) Thread Pitch: UNF-2B Type of Filter: Spin-on Threads: 3/4-16 Note:
Unfortunately, the thread pitch 3/4-16 is not a very common for fuel filters, the 3389 costs about $15 and is the same size as the oil filter. If the threads were 1-14 a filter could be had that was twice the size and half the price. It is probably cost effective to buy a heated DAVCO fuel filter rig in order to use a filter that is twice the size and half the price.
