Part #: 9 - 301 - 0791. DeatschWerks has revamped the DW300 fuel pump to deliver greater flow without a significant rise in current draw. It offers a 26% increase in peak flow and a 20% average increase. The low amperage draw keeps pump temperatures down, extends pump life, and reduces stress on the OE wiring. The flow improvements are engineered for high - pressure situations (60 - 90psi), where forced induction applications need it most. At low pressures (30 - 50psi), fuel flow is limited to minimize heat in return fuel systems. This dual - zone design creates a flatter flow curve, enhancing both performance and reliability for supercharged or turbocharged setups. The DW Advantage includes a flow rate of 340 liters per hour (90 gallons per hour), in - tank application - specific fitment, ethanol compatibility, a 3 - year no - fault warranty, and a quiet and reliable turbine impeller.
Using the Deatschwerks DW300 fuel pump is straightforward. First, make sure to follow the installation instructions in the install kit carefully. It's designed to fit specific in - tank applications, so ensure it's the right fit for your Subaru model (WRX/STI 1993 - 2007, Forester/XT 1997 - 2007, or Legacy 1990 - 2007). When using the pump, note that it's optimized for high - pressure situations but also works well at lower pressures. Since it's ethanol - compatible, you can use it with ethanol - blended fuels. For maintenance, keep an eye on the pump's performance. If you notice any unusual noises or a decrease in flow, it might be time to check it. The pump comes with a 3 - year no - fault warranty, so if you have any issues during this period, reach out to the manufacturer. And remember, because it has a low amperage draw, it's less likely to overheat, but still, avoid extreme conditions that could stress the pump.
