The D-Max Flow Enhancer has been designed to provide your Duramax engine with a constant 8 PSI fuel pressure, aiding the injection system by reducing the amount of work your factory injection pump has to perform, extending its expected life and improving performance gains from aftermarket tuning products. Since the D-Max Flow Enhancer is a "pusher" pump, all fuel is placed under pressure, helping prevent the introduction of air and vapor.
