Aeroflow Performance make this replacement pre filter sock/screen. It is specifically designed for our 450 / 525lph EFI 40mm diameter fuel pumps (it may also suit similar branded fuel pumps). This 65-micron pre-filter sock press-fits and uses a safety lock washer. It has a skeleton structure inside it making it less susceptible to cavitation. This same screen also suits our in tank direct fit fuel pump modules for Nissan, Mitsubishi, Subaru and Ford.
