Installation Guide
Remove old filter by unscrewing counterclockwise. Apply thin film of clean fuel to new filter's gasket. Spin on clockwise until gasket contacts, then tighten additional 3/4 turn by hand. Prime fuel system and check for leaks before starting engine. Pro tip: Pre-fill the new filter with clean fuel to reduce cranking time.
Frequently Asked Questions
Q: How often should I replace the fuel filter water separator?
Replace every 100 operating hours or annually, whichever comes first. In high-humidity or older tank environments, quarterly replacement is recommended.
Q: Will this fit my outboard motor?
The UF-10K uses standard spin-on mounting compatible with most marine filter heads. Verify your existing filter's thread size and gasket diameter for fitment confirmation.
Q: How do I drain accumulated water?
Use the built-in drain valve at the bottom of the housing. Drain into a suitable container when water reaches the indicated level, typically monthly as preventive maintenance.
