I have been getting reports of filter plugging problems from areas around the country. The problem is not unique to any brand of fuel, supplier, or geographic area. Many of the "experts" are saying it is the result of the introduction and use of ultra-low sulfur diesel. It is not caused by using biodiesel. Unfortunately, ULSD is, or will be, the only type of diesel available now and in the future.
The filter plugging is more than likely the result of bacteria, algae, or fungi growing in the tank. It can be in your storage tank, service tank, or equipment tank. In years past the diesel had much higher concentrations of sulfur. Not only was this good for lubrication, sulfur also helped kill the bacteria and other organisms growing in your tank. Diesel fuel combined with moisture (which is present in most tanks) can create an ideal atmosphere for the growth of these organisms. The highly sophisticated fuel systems in todays' equipment will not allow these organisms to flow through and burn like the equipment of old. There are preventive actions you can take to avoid costly downtime. First, make sure you have clean filters on all pumps, including service tanks. Second, change these filters before you start in the spring and again before you start in the fall. Change filters on your equipment at regular intervals. If possible, drain any moisture accumulations in your tanks annually. If you do have problems, treat your fuel with a biocide such as "Killem". Times have changed and clean fuel is going to be extremely critical now and in the future. Downtime and replacing filters is very costly. A great plan would be to contact Shelly Sundeng with Optic Fuel Clean of West Fargo. They can filter out contaminants from your tank and give it a thorough cleaning all the way to the bottom of the tank. She can be contacted at 281-5071 or look them up on the web at www.cleanfuelguys.com. They are highly recommended by Cenex. Dale Beck |
