This fuel filter sock is mounted directly on the fuel pump’s 22 millimetre intake and works as the first filtration of the fuel before it reaches the pump itself. The filter sock helps prevent dirt, particles and other impurities from being drawn into the pump, where they can reduce flow or affect the pump’s service life.
This filter sock fits fuel pumps with a 22 millimetre pump inlet. The 22 millimetre connection refers to the pump intake where the filter sock is mounted, not the outer dimensions of the filter.
A clean and properly functioning pre-filter is important for stable fuel supply and for protecting the fuel pump against contamination from the tank. This is especially relevant on older vehicles, motorsport cars, tuning projects and other high-performance fuel systems where fuel quality and flow are critical.
When servicing or replacing a fuel pump, it is often recommended to replace the filter sock at the same time to ensure optimal operation and maximum protection of the fuel system. If the filter sock becomes clogged, it can restrict the fuel pump supply and affect the performance of the fuel system.
