Aeromotive 12602 Pro Series 100 Micron Filter Element

What is the difference between a 100 micron and 10 micron fuel filter?

• A 10 micron filter is a finer filter and will catch smaller contaminants, but is too fine to be placed between the tank and fuel pump.  A proper fuel system will use a 100 micron filter between tank (or cell) and fuel pump to catch large contaminants and protect the pump.  It will then have a 10 micron filter placed between pump and injectors to keep debris out of the injectors and engine itself.
