Fuel pump strainers act as a first line of defense against fuel system contamination. Strainers filter out common contaminants found in gasoline such as dirt, dust and other particulate matter, as well as gasoline varnish. Quantum fuel pump strainers feature multiple layers of strainer media to filter progressively smaller particle sizes. The expanded surface area provides enhanced filtration, extending the life of the fuel pump.

Restricted fuel flow through a clogged strainer causes the fuel pump to work harder, reducing pump longevity. Strainer clogging is among the top causes of fuel pump failure making it important to replace your strainer regularly - before problems arise. We recommend replacing fuel pump strainers in powersports applications once a year as part of a preventative maintenance plan.

Features:

• Designed with gradient density to meet or exceed OE specifications
• Designed to ensure optimal filtration to prevent fuel system contamination
• Strainer material tested and validated for capacity and efficiency by accredited third party
