A clogged fuel filter starves the engine of performance and efficiency; changing the filter at regular intervals is important to keep it running in ship-shape. Racor Spin-On replacement elements are extremely effective and make it easy. The element body is powder coated to resist corrosion and is easy to grip for removal and installation. Deep pleats in the media trap debris and provide an extended service life. Each Spin-On element features Aquabloc which removes nearly 100% of the water by repelling moisture and directing it downward into the bowl with larger particles for quick removal through the drain in the bowl. Gaskets and O-rings are included with replacement elements to provide the best possible seal between the mount head and re-usable bowl. We recommend having spares aboard to be prepared for unexpected clogs caused by tainted fuel from the dock or debris and algae from the tank that has been stirred up by rough seas.
