Quieter and easier to fit than Walbros, the Bosch 040 fits inside a B6 Audi's fuel tank. It fits and operates in stock position when combined with an adapter ring (no longer offered here). Ideal for keeping high-boost fuel rail pressure when running big injectors. Supplied bare with outlet fitting available separately. No surge tank is needed for faultless operation.
