How often should I clean the filter element?

The cleaning interval depends on the fuel quality and operating conditions. Fuelab recommends inspecting the filter element regularly and cleaning it when you notice a buildup of contaminants. A drop in fuel pressure can also indicate that the filter needs cleaning.

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 lines, which can improve starting and reduce the risk of vapor lock.

What size fuel line is compatible with this filter?

This filter uses -10AN inlet and outlet ports. You will need -10AN fuel lines and fittings to connect it to your fuel system. Be sure to use fuel-compatible hose when installing.
