Frequently Asked Questions

Q: Does this filter include the water sensor?
A: This is the filter element only and does not include the water sensor. The water sensor threads into the bottom of the filter housing and is typically reused during filter replacement.

Q: How often should I drain water from the separator?
A: Check the water separator weekly or every 1,000 km, especially if you operate in humid climates or use biodiesel blends. Drain immediately if water is visible in the sight glass or drain valve.

Q: Will this filter fit both early and late model diesel engines?
A: Yes, this filter design was used across Toyota's entire diesel range from approximately 1979-2006. However, some very early diesel models (pre-1984) may use different filter configurations. Always verify your existing filter matches before ordering.

Common Symptoms of Clogged Fuel Filter or Water Contamination

• Loss of engine power, especially under load or acceleration
• Rough idle, misfiring, or hesitation during operation
• Difficult starting or extended cranking time, particularly when cold
• Engine stalling or unexpected shutdown while driving
• Water warning light illuminated on dash (if equipped with water-in-fuel sensor)
