Fuel Filter
Often overlooked in EFI installations, the fuel filter must have the capacity, filtering efficiency and
burst strength to withstand the pressures of an EFI system. It must be able to flow the amount of
fuel that matches the maximum fuel pump output. The filter is always located after the fuel pump,
however it does not matter if it is positioned in the front or rear of the vehicle. (We prefer to put it
toward the front for easy serviceability.) AEM carries fuel filters for high-powered engines, which
use an easy to find, high volume, replaceable element.
It is imperative that a pre-filter be mounted to the fuel pick up in the tank. These filters are very
high volume and create very little pressure drop. The use of a pre-filter ensures long fuel pump
life and can eliminate low flow conditions caused by debris entering the pump inlet.
