Which fuel pump and blow-off valve do you recommend for a stock Mitsubishi Lancer Evo 8?

For the fuel pump we recommend the AEM 50-1000 high flow in-tank pump. For the blow-off valve there are two excellent brands: GReddy (FV type and Type FV/BFV kits made for the Evo 7/8/9) and Turbosmart (Kompact Plumb Back 34 mm, which recirculates the air quietly, or Kompact Dual Port 34 mm, which gives part of the characteristic vent sound). All are original, reliable products; the choice is mainly about sound.
