Deatschwerks DW440 Fuel Pump w/ Install Kit + PWM Speed Controller Subaru WRX 2008-2014 / STI 2008-2021

Part #: 9 - 441 - C103 - 0910. The brushless DW440 fuel pump is a power - packed solution in a compact size. Running on a standard 13.8v battery voltage, it pumps an impressive 440LPH at 40PSI, capable of supporting up to 1000hp on gas and 750hp on e85. If you need even more flow, the 40amp controller and brushless design let this pump work well at voltages higher than the typical 13.8v battery voltage. It has been endurance - tested at up to 24v, and at a recommended max intermittent voltage of 20v, it flows 620LPH at 40psi. The C103 PWM modulated controller enables full control of your DW440 through your existing OE or aftermarket fuel pump control module's PWM signal. Features include a compact 4 - inch inlet - to - outlet size, bulkhead wiring, and a venturi outlet. What's included: a 440lph in - tank brushless fuel pump, a PWM Speed Controller, and a 9 - 0910 Install Kit.

Using the Deatschwerks DW440 fuel pump is straightforward. First, use the included 9 - 0910 Install Kit to install the 440lph in - tank brushless fuel pump in your Subaru WRX or STI. Connect the PWM Speed Controller to your existing OE or aftermarket fuel pump control module to take full advantage of the C103 PWM modulated control. When operating, make sure to keep an eye on the voltage. The pump is tested at up to 24v, but the recommended max intermittent voltage is 20v. Don't exceed this recommended voltage for long - term use to avoid damage. For maintenance, regularly check the bulkhead wiring for any signs of wear or damage. Also, ensure the venturi outlet is clean and unobstructed. If you notice any issues with the pump's performance, such as reduced flow, it might be time to have it inspected by a professional.
