The Radium Engineering high flow fuel filter has a 3 piece body that is CNC machined from 6061 aluminum and Type-II anodized for maximum corrosion resistance. Both removable end caps feature large -10AN ORB female threaded ports for high flow plumbing. Includes your choice of internal filter element which (depending on the element) can be replaced or reused.Vehicle Fitment:• Universal ApplicationInstall Instructions: Download PDFMore Details:The fuel filter comes preassembled with Viton O-ring seals for all fuel types including gasoline, diesel, methanol, ethanol, and alcohol blends such as E85. High fuel pressures of 150psi+ can safely be used with negligible pressure drop.The filter features a large 4.2" x 1.75" element maximizing flow without sacrificing filtration. The large elements also hold a lot of contaminants without becoming a restriction, resulting in a very long service life.Mounting options are available, listed below, for either a universal install or vehicle-specific for the Evo 8/9, Evo X, Focus RS and MKIV Supra. (Sold separately)Includes:• Aluminum Filter Body• Your choice of Filter Element Mounting Options: Mounts are not included. Universal and vehicle-specific options and kits are listed below, sold separately.

The pressure drop was found by measuring the inlet and outlet pressures at different flow rates. Notes: Radium PN 20-0220-01 was discontinued in December 2020.
