What is the purpose of the check valve?

The check valve prevents fuel from draining back into the tank when the engine is off. This helps maintain fuel pressure and makes starting easier, especially in systems with long fuel lines or high-mounted fuel rails.

What fuel types are compatible with this filter?

The stainless steel filter element is compatible with all fuel types, including gasoline, diesel, ethanol, and methanol. This makes it a versatile choice for a variety of applications.

How often should I clean or replace the filter element?

The service interval depends on fuel quality and pump volume. Inspect the filter regularly and clean or replace it when you notice a drop in fuel pressure or flow. A clogged filter can damage your fuel pump.
