1. Fuel handling Best Practices
Pete Probst

2. Buy ASTM spec fuel… And keep it in spec!
Handling and storage issues can turn great fuel into bad fuel
Water
Microbes
Oxidation Stability
Total Acid Number
Sediment
Sludge

3. Underground Storage

4. Above ground Storage
Keep tanks as full as possible to reduce moisture in headspace
Check for rust and sediment
A dissicant filter on vent can reduce moisture
Don’t use lead, brass, copper, bronze, zinc or galvanized metals in fuel systems

5. Equipment inspections
Chronic water infiltration can decimate fuel quality
The biodiesel program will likely take the blame

6. Periodic fuel system inspections
Lab test fuel
Remove water
Apply biocides to kill bacteria, mold or yeast

7. Periodic fuel system inspections
Don’t rely on fuel tank monitors to detect water

8. Filter issues
Slow dispensers or complaints from drivers will be the first indication of a filter issues

9. Tank cleaning Remove water and sediment Apply biocides as necessary
Remove dead biomass

10. Routine maintenance
- Test for water monthly along with State Fire Marshall inspection requirements
- Visually inspect fuel periodically with a bacon bomb sampler
- Add antioxidants to fuel stored longer than 6 months – 1 year.
Get fuel lab tested to monitor conditions
Oxidation Stability
Acid Number
Microbial Content
