Not only is this billet aluminum inline filter extra long (11”), but it’s also 2-1/4” in diameter to provide excellent filtration for a high volume fuel flow. Nominally rated at 28 GPM with AN-16 lines, it’s commonly installed between the fuel tank and pump using System 1’s billet frame mount clamps. Features a red anodized housing with a 35-micron filter and choice of AN-10, AN-12 or AN-16 fittings and either a Buna (alcohol) or Viton (nitro or gas) o-ring.
