DW400 In-Tank Fuel Pump

The DeatschWerks DW400 is a universal in-tank fuel pump engineered for high-performance applications requiring consistent fuel delivery. Its design incorporates a quiet turbine impeller that is compatible with pulse width modulated (PWM) pump drivers, ensuring smooth operation. Furthermore, the pump is constructed with carbon commutators and fully encapsulated armatures, making it ethanol-compatible. Engineered for superior performance, the DW400 features high-torque motors that excel at maintaining fuel flow even under increased pressure, outperforming many competitors. Its low amperage draw helps to minimize operating temperatures, thereby maximizing the pump's lifespan and reducing stress on the vehicle's electrical system. The pump has a flow rate of 415 LPH at 40 PSI and a maximum pressure of 120 PSI. Installation of the DW400 requires some considerations. Due to its high flow rate (400+ LPH), it draws substantial current (16-20 amps), so ensuring your vehicle's wiring can handle this load is crucial. A DeatschWerks hardwire kit (FPHWK) is recommended. The DW400 has a 46mm diameter, which may necessitate modifications to the fuel pump module on some applications, as standard in-tank pumps are typically 39mm. Additionally, the DW400 does not feature an internal check valve, so an in-line check valve might be required for optimal engine starting in certain setups. This is a universal fitment pump, meaning it is not application-specific. A universal install kit, including a filter and electrical connector, is provided to aid in installation. DeatschWerks backs the DW400 with a 3-year no-fault warranty.
