How often should I clean the filter element?

The cleaning interval depends on the fuel quality and pump flow rate. Inspect the filter regularly, especially after initial installation, and clean it when you notice a buildup of debris. A drop in fuel pressure can also indicate a clogged filter.

What is the purpose of the check valve?

The check valve prevents fuel from flowing back into the fuel tank when the pump is not running. This helps maintain fuel pressure in the lines, which can improve starting and throttle response.

What size fittings do I need to connect this filter to my fuel lines?

This filter uses -8AN inlet and outlet ports. You will need -8AN fittings that are compatible with your fuel lines. Be sure to use fuel-compatible hose and sealant.
