DeatschWerks 2002-2004 Subaru WRX/STI 415LPH DW400 In-Tank Fuel Pump

DW400 In-Tank Fuel Pump by DeatschWerks

DeatschWerks' in-tank fuel pumps feature a turbine impeller designed for quiet and reliable operation, compatible with pulse width modulated pump drivers. Carbon commutators and fully encapsulated armatures ensure ethanol compatibility. With high-torque motors, these pumps maintain flow at higher pressures better than competitors, while low amperage draw minimizes temperatures for extended pump life and reduced stress on OE wiring. Each kit includes electrical connectors and accessories for easy installation. Backed by a 3-year no-fault warranty, trust DeatschWerks for superior fuel pump performance.

Features

• Turbine Impeller Compatible w/ Pulse Width Modulated Pump Drivers

• High-Torque Motors with a Low Amperage Draw
• Minimizes Temperatures, Maximizes Lifespan and Reduces Stress
• Includes an Installation Kit

Additional Considerations

• Wiring – A 400+ LPH pump draws substantial current (16-20 amps at typical operating pressures). Make sure your chassis wiring is up to the task of delivering this much current. A DW hardwire kit (part number FPHWK) is an inexpensive insurance policy.
• Size – The DW400 is a 46mm diameter pump. Standard in-tank pumps are 39mm diameter. Modifications to the fuel pump module will be necessary on some applications.
• Check-Valve – the DW400 does not have in internal check valve. An in-line check valve may be necessary for easy engine starts in some applications.
