James,
Check out this link: http://www.dogwoodenergy.com/. It’s for a company that manufactures stills for producing ethanol. Ethanol can be used for use as a diesel fuel extender. The downside is that the still must be registered with the BATFE, including the street address and the location [of the still] on the property.
As an aside on diesel fuel: I worked for an earthmoving company in Florida and they maintained diesel fuel tanks on the premises. One of the problems they had with diesel that they didn’t have with gasoline was that bacteria would grow in diesel and clog the filters. It wouldn’t grow in gasoline. Just something to be aware of. – Mark A.
JWR Replies: There is a commercially-made diesel additive called “PRI-D Diesel and Kerosene Fuel Saver.” It acts as both a fuel stabilizer and antibacterial. Diesel treated with PRI-D will store for at least five years. Both PRI-D and PRI-G (for gasoline) are available from Ready Made Resources (one of our first and most loyal advertisers), Nitro-Pak (one of our affiliate advertisers), and several other Internet vendors.
