Periodically (annually is recommended) drain water and sediment from the fuel tank. Drain and flush sediment from the fuel tank at least every 12 months or more frequently if fuel quality or type of fuel dictates.

Since Ultra-Low Sulfur Diesel (ULSD) fuel tends to absorb more water and engines are operating at higher temperatures, microbe growth in the fuel tanks has become more prevalent. Microbe growth results in more contaminants in the fuel and reduces fuel filter life. Since fuel tank draining does not remove all microbes, fuel tank draining alone will not eliminate the problem.

If microbe growth is found in the fuel:

1. Drain and clean the fuel tank(s) every 12 months or more often. Clean the tanks with a professional fuel tank cleaning system (available through your dealer) or have your dealer perform the service for you.

2. Treat the vehicle fuel tanks and bulk tanks regularly with a biocide from a reputable vendor.

3. Purchase fuel only from vendors that pretreat their fuel with biocides.

4. Periodically test the fuel supplied by your fuel vendor for the presence of microbes.;
