Good To Know
Q: What are signs that this fuel filter needs replacing? A: Symptoms include hard starting, rough idling, loss of power under load, or visible water in the fuel separator. Replacing this filter when these signs appear can restore engine performance and prevent damage to injection components.
Q: Can this filter be used with modern diesel fuels containing biodiesel? A: This filter is designed to handle standard diesel fuels and low-blend biodiesel mixtures. For high-biodiesel blends, more frequent filter changes may be necessary due to the solvent properties of biodiesel.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
