Replacement 10-Micron Fuel Filter Element

The HOLLEY Replacement 10-Micron Fuel Filter Element (part number 162-556) is a precision replacement filter designed for use with HOLLEY billet fuel filter housings. This 10-micron paper element with integrated O-ring provides reliable contamination removal for carbureted and fuel-injected engines running on gasoline. The 10-micron filtration rating removes particles small enough to prevent fuel injector clogging and carburetor damage while maintaining adequate flow rates for consistent engine performance across a range of engine displacement and fuel pump combinations.

The element's paper construction offers the industry-standard approach to fuel filtration, balancing fine particle capture with flow capacity. The integrated O-ring seal ensures a leak-free fit within compatible HOLLEY billet filter housings, eliminating the need for separate gasket replacement. At 0.07 lbs and measuring 2.1 x 2.05 x 3.2 inches, the element is compact enough to fit standard underhood fuel system configurations. Replacement is straightforward: the element slides into the filter housing, and the O-ring seats automatically, making it a practical service item for scheduled fuel system maintenance.

This filter element is essential for builders and enthusiasts maintaining high-performance fuel systems where fuel purity directly impacts engine reliability. Street machines, race cars, and classic cars relying on HOLLEY fuel delivery components benefit from regular filter element replacement to prevent sediment buildup and fuel system corrosion. The 10-micron specification strikes a practical balance for gasoline engines: fine enough to protect modern fuel injectors and carburetors, but not so restrictive as to create flow resistance on stock or lightly modified engines.

Fuel system maintenance is a routine but critical aspect of engine care. Over time, fuel tanks accumulate moisture, sediment, and oxidized fuel residue that can restrict flow and damage precision components. Regular replacement of the fuel filter element—typically every 12 months or after extended storage—keeps fuel clean and engines running smoothly. This OEM replacement element ensures exact fitment with your HOLLEY fuel filter housing and meets the original specifications for flow rate and filtration performance.
