Part #: 9 - 301 - 0791. DeatschWerks has revamped the DW300 fuel pump to deliver greater flow without a big jump in current draw. The new pump offers a 26% increase in peak flow and 20% more on average. Its low amperage draw keeps pump temperatures down, extends pump life, and eases stress on the OE wiring. The flow enhancements are designed for high - pressure needs (60 - 90psi), perfect for forced induction applications. At low pressures (30 - 50psi), fuel flow is limited to reduce heat in return fuel systems. This dual - zone design creates a flatter flow curve, boosting both performance and reliability for supercharged or turbocharged vehicles. The DW Advantage includes a flow rate of 340 liters per hour (90 gallons per hour), a precise in - tank fit, ethanol compatibility, a 3 - year no - fault warranty, and a quiet, reliable turbine impeller.
Using this Deatschwerks DW300 fuel pump is straightforward. First, make sure your vehicle is one of the compatible models (WRX / STI from 1993 - 2007, Forester / XT from 1997 - 2007, or Legacy from 1990 - 2007). Follow the instructions in the install kit carefully when putting it in the tank. As for maintenance, keep an eye on the fuel quality. Use clean, ethanol - compatible fuel to avoid any issues. Since it has a low amperage draw, it won't overheat easily, but still, don't run the vehicle for extremely long periods without breaks. If you notice any unusual noises or a drop in performance, check the pump right away. The 3 - year no - fault warranty gives you peace of mind, but regular checks can help keep the pump running smoothly for a long time.
