How often should I replace the filter element?

Fuelab recommends inspecting the filter element regularly and replacing it as needed. The replacement interval depends on fuel quality and how much the vehicle is driven. A clogged filter will restrict fuel flow and reduce engine performance.

What size are the inlet and outlet ports?

This Fuelab fuel filter uses -6AN inlet and outlet ports. These are a common size for aftermarket fuel systems. Be sure to use compatible fittings and hose when installing.

Is this filter compatible with E85 fuel?

Yes, the Fuelab 818 fuel filter is compatible with gasoline, diesel, and E85 fuels. The filter element and housing materials are designed to withstand the corrosive properties of alcohol-based fuels.
