Radium High Flow Fuel Filter The Radium Engineering High Flow Fuel Filter is a universal inline fuel filter CNC-machined from 6061 aluminium with Type-II anodising for maximum corrosion resistance. Both removable end caps feature large 10AN ORB female threaded ports for high-flow plumbing. Viton O-ring seals are used throughout for compatibility with all fuel types including gasoline, diesel, methanol, ethanol, and E85. Safe for fuel pressures up to 150 PSI with negligible pressure drop. The large 4.2" x 1.75" element maximises flow without sacrificing filtration, and holds a high volume of contaminants before becoming a restriction — resulting in an exceptionally long service life.
