    QUESTIONS & ANSWERS

    • Q: would a tune be required on a 2004 wrx ?  chris04wrx7 months ago

      would a tune be required on a 2004 wrx? currently on a td06 20G turbo, mishimoto aluminum radiator and tomei exhaust with a gs boost controller no other upgrades currently. would this be overkill for the car when it comes to fuel? or will the ecu tell the car to retart the pressure of the pump?
      • 0 of 0 people found the following answer helpful

        A:  You should not need to get a tune with just the fuel pump, the ECU will adjust as needed with pressure.

    • Q: Fitment for 2011 WRX STI  Niran2 years ago

      Hi, will this pump drop into the factory fuel cradle? Or will modification be required on the 2011 WRX STI?
      • 0 of 0 people found the following answer helpful

        A:  This is a universal fuel pump, some modification may be needed to get it to fit correctly.

        A:  Hello Niran, The DW400 will not be a direct fit into the 08-18 STI assembly. The physical size of the pump is much larger than the compact pump that comes in the OE assembly. Significant modifications or a different pump assembly/hanger design will likely be required.
