Billet 4500 Fuel Filter -12an 100-Micron 260GPH

The Holley Billet 4500 Fuel Filter with -12AN 100-Micron 260GPH capacity is a high-flow inline fuel filtration solution engineered for carbureted and fuel-injected performance engines. This filter is designed to deliver clean fuel to your engine while sustaining flow rates up to 260 GPH—ideal for street, strip, and naturally aspirated racing applications where fuel purity directly impacts engine longevity and performance consistency.

At 100 microns, the stainless steel media effectively filters particulate matter without restricting fuel delivery, which is critical for carburetor and injector reliability. The -12AN female O-ring inlets and outlets provide secure, leak-free connections to fuel lines and carburetors, matching the industry standard for high-flow fuel systems. The anodized aluminum housing resists corrosion and reduces weight compared to cast-iron alternatives.

This compact filter, weighing just 0.75 lbs and measuring 2.3 × 2.2 × 5.8 inches, installs in-line between the fuel pump and carburetor with minimal clearance issues. It serves builders and enthusiasts running Holley carburetors and modern fuel delivery systems where bulk, debris, and water contamination threaten drivability and reliability. The 260 GPH capacity supports aggressive cam timing and high-RPM operation without starving fuel circuits.
