How often should I clean the filter element?

The cleaning interval depends on fuel quality and pump type. Inspect the filter element regularly, and clean it when you see significant debris accumulation. A good rule of thumb is to check it every 6 months or 6,000 miles.

What is the purpose of the check valve?

The check valve prevents fuel from flowing backward through the filter when the fuel pump is not running. This helps maintain fuel pressure in the system and prevents vapor lock, especially in hot weather.

Can I use this filter with any type of fuel?

This filter is compatible with gasoline, diesel, and ethanol-blended fuels. However, always check the compatibility of all fuel system components with the specific fuel you are using.
