    Walbro 255lph fuelpump for Subaru Sti GRF A-Line 3 years ago
    5out of 5stars

    price was reasonably cheap, product came in proper packaging, installation was straight forward with the exception of modifying the pump housing as the walbro was bigger than the oem pump. installation took around and hour+ car felt quite responsive as ive tuned the car prior to the pump installation.

    • Q: 2006 Subaru Legacy GT  Corvo3 years ago

      Does this fuel pump fit my car without modification?
    • Q: When is this needed?  sikknt4 years ago

      I'm running a 20GXTR and 750cc injectors, my tuner swears I don't need it but I see so many other STi's with my similar setup with this pump.
    • Q: Walbro 255LPH rating  AMX4 years ago

      What's the max at the wheel power can this pump support for 07 sti?
      • 0 of 1 people found the following answer helpful

        A:  A fuel pump doesn't get rated for power, its classified by the amount of fuel it can provide. Normally this pump is good for around 365hp. Check with your tuner to see if this will be what you want for your power goals.

    • Q: accessories to make it a kit  Kevroq5 years ago

      Will this fit 2015 STI and what other stuff will I need for the install (beside injector)
      • 1 of 1 people found the following answer helpful

        A:  This is a universal part, so we are unable to confirm fitment. This pump may require modification to the stock fuel pump housing in order to fit. You would need to purchase the universal install kit in addition to the pump.

    • Q: Drop in?  Racingthatsubbi5 years ago

      Does this drop in to a 07 sti and replace the stock pump or do I need to get the kit?
      • 0 of 1 people found the following answer helpful

        A:  This should fit your sti with no modification, and we recommend purchasing the install kit as well.
