Frequently Asked Questions (FAQs)

1. What are the two types of fuel filters?

1) There are two types of fuel filters depending on how they are attached during replacement: spin-on filters and cartridge filters. The filter medium is contained in a metal case which is threaded on the bottom.

2. How many microns is a factory fuel filter?

THE FACTORY FUEL FILTER An OEM filter is usually around the 10 – 12-micron mark (0.01 to 0.012mm), but not exclusively greater than 10; sometimes as small as five microns. So they will filter out exceptionally small particulates and debris.

3. How many microns is a E85 fuel filter?

High pressure EFI applications require a 10-micron cellulose filter to prevent debris from clogging fuel injectors. Pre-filters for EFI pumps use a stainless mesh 100 micron filter. However, if your plans call for running E85 or methanol fuel, make sure to always use stainless steel mesh fuel filters.
