This is one of the safest and most effective fuel filters made for racing applications. The Fram HPGC-1 filter element has a nominal 5 micron rating* to ensure a clean fuel supply. Designed for flow rates up to 90 GPH with minimal pressure drop (0.2 psi @ 45 GPH). 

* A 5 micron particle is smaller than the diameter of a red blood cell.
