Fuel Filter -12 45 Micro

The Fuel Filter -12 45 Micro by Peterson Fluid is a precision fuel delivery component engineered for high-performance and modified automotive systems that demand reliable filtration under demanding conditions. As a mechanic who has seen countless fuel system failures traced back to inadequate filtration, I can attest that this micro-rated filter protects fuel injectors, carburetors, and fuel pumps from particulate contamination that would otherwise cause lean running conditions, injector clogging, and costly engine damage. Whether you're running a turbocharged engine, a carbureted hot rod, or a fuel-injected performance platform, this Peterson Fluid filter serves as your first line of defense against fuel system degradation.

Built with a 45-micron filter media, this unit provides exceptional flow rates while capturing contaminants small enough to damage precision fuel delivery systems—a critical balance that separates quality fuel filters from budget alternatives. The compact 3.3 x 3.3 x 9.7-inch design allows flexible installation in tight engine bays, and at just 1.1 pounds, it adds negligible weight while delivering robust filtering performance. Peterson Fluid's reputation for aerospace-grade fuel system components ensures consistent construction quality and reliable pressure retention across temperature variations common in high-output engines.

This fuel filter is ideal for street performance builds, vintage fuel-injected restorations, and any modified engine where fuel system reliability directly impacts drivability and longevity. The -12 designation indicates a -12 AN thread size, a standard in custom fuel system plumbing that makes integration straightforward for builders already committed to premium-grade component selection. Installation requires compatible -12 AN fuel line fittings and proper orientation for optimal flow direction—always reference your specific fuel system configuration before ordering to ensure correct fitment for your application.
