This kit, which includes (4) Brand New Driven Diesel T-304 STAINLESS STEEL High Flow Banjo Bolts and (4) copper crush washers, replaces the stock restrictive banjo bolts in your 7.3L Powerstroke Diesel. The larger passages through the Driven Diesel 7.3L banjo bolts will reduce restriction and increase flow to the fuel rails, resulting in less turbulence in the fuel and improved support for larger injectors or other horsepower modifications.
