The ultimate filter for highly-boosted EFI applications, it’s designed to flow 40 GPM while providing 10-micron filtration to keep fuel injectors flowing perfectly. Please note that they are designed to use System 1’s remote mount, which has two 5/16-18 bolt holes on a 2” center and should be mounted horizontally, or with the AN fittings at the top and cap at bottom. These filters are offered only in a black anodized finish and require AN-12 lines. NOTE: Do not leave filter full of fuel from week to week.
