Tips for Fuel Filter Maintenance Intervals
- Drain water from your primary filter daily when refueling.
- Carry a spare set of fuel filters in case you receive a bad load of fuel.
- Never switch to more open filters to get longer filter life, it will reduce fuel pump
and injector life.
- If using biodiesel, make certain your fuel supplier meets current fuel standards.
- Ensure that your engine is compatible with the concentration or percent biodiesel you wish to use.
- Use bulk filtration on your own fuel tank, because removing contaminants before they reach the vehicle is the best. |
