    DeatschWerks DW300 Series Fuel Pump w/ Install Kit ( Part Number: 9-301-0791)
    Great for all your fueling needs 8 months ago
    Little louder than stock when it's primed, but with the noise the car makes while it runs, you can't tell the pump is even running.

    2004 Subaru Impreza Wrx STi 2 years ago
    Bought this fuel pump so I can upgrade my injectors for more power to later go to E85. The fuel pump went in just like it was suppose to with no problems.

    • Q: Non turbo 2.5i  Yaboyrumble3 months ago

      Would the dw300 work fine on my na 2.5i or would 255 be better??
      • 0 of 0 people found the following answer helpful

        A:  Unfortunately, we have it as a universal fitments so we have no confirmed fitment for your car, however, these pumps are meant for turbo charged vehicles pushing big power. This would give you far more fuel than you would ever use.

        A:  I have the AEM 340lph pump on my NA 06 2.5i, works just fine. Open loop runs a little bit rich but the ECU compensates for up to +/-40% air and fuel. No tune yet, but runs better than the OEM fuel pump in my opinion. You can do a bigger pump with OEM injectors without an issue. The amount of fuel that will enter the cylinders depends on the size of the injectors, not the pump, but big injectors with a small fuel pump will burn up the pump. Too big fuel injectors and pump with too little air will cause saturation of the cylinders and vice versa.

    • Q: Dw 300 fuel pump   2004subie 4 months ago

      Will this be good for my pump gas 400whp wrx stock location gt3076r
      • 1 of 1 people found the following answer helpful

        A:  I would suggest doing a Walbro 450 pump, that way you have plenty of fuel and you can always shoot for more power down the line.

    • Q: HP/Injectors  502sti5 months ago

      I was looking at this pump for my 07 sti build. My goal is 500whp with supporting mods on e85, would this pump delivery enough fuel for a 500whp application? Also what size injectors would be best for my goals? Also, Deatsch Werks calculator wasnt working for me.
      • 0 of 0 people found the following answer helpful

        A:  This pump would not be a good fit for 500whp, I would suggest doing a Walbro 450 pump with Injector dynamics 1700cc injectors.
