Features & Product Details

When the injectors and fuel pump are upgraded the stock fuel pressure regulator may not be enough to suit the required pressures for the new setup. The stock FPR is preset from the factory and is non adjustable so it will limit your options. The TOMEI Fuel Pressure Regulator will ensure stable pressures are supplied with the oversized diaphragm. This special design has proven to maintain the required pressure levels with any adjustments made.

Comes with 6AN adapters and #8 nipple connectors.

It will also come in the black anodized finish to blend in well with your engine bay.

Installed on '07 STI. This regulator looks good and install was easy. My tuner said, I could have used stock regulator and been fine, even with all my upgrades, but it looks so good when I lift up the hood.

Looks great under the hood, works as it should. The only problem I had was that way it’s set up, it limites you on mounting options unless you change your set up. I ended up modifying the bracket to fit for now.

Fixed my STI Stumble 4 years ago
QT
This FPR mostly fixed my 2012 STI stumble. I used this FPR to replace my factory/OEM fuel line system. I got the stumble after upgrading injectors and fuel pump. With this FPR and a tune, the stumble is now gone. FPR works perfect. No issues or leaks in over a year.

Great Regulator! 5 years ago
EKev122140380
Ordered this for my 13 STI with 1000cc ID's and Walbro 255. With the stock FPR had some issues with lean AFR's. Swapped to this FPR and the 42086FE040 and 42086FE030 dampers from an 06 STI and everything is perfect now! Great quality, fast shipping. What more can you ask.

  • Q: Fuel Damper delete  Travannoy6 months ago

    I'm looking for an affordable way to eliminate my fuel line dampers, as they seem to be prone to failing. Is this pressure regulator able to do so?
    • 0 of 0 people found the following answer helpful

      A:  I would recommend consulting your tuner for their thoughts on this, as fuel line damper deletes are fairly uncommon, and may not be best for your particular setup.

  • Q: Flow rate  riko9 months ago

    Does this have it's own preset flow rate since it is not adjustable? If so, how much more % flow is it over OEM fuel regulator?
    • 0 of 0 people found the following answer helpful

      A:  Unfortunately, we do not have this info readily available and would recommend contacting Tomei directly. Sorry for any inconvenience..

  • Q: 2006 forester xt  Hinkes3 years ago

    Is this FPR a 1:1 regulator or does it stay at the same preset pressure?
    • 0 of 0 people found the following answer helpful

  • Q: 2004-2007 STI  Patrick924 years ago

    What else do I need to run this for my 2004 STI? Do I need the adapter?
    • 0 of 0 people found the following answer helpful

      A:  Tomei's regulator adapter does make installation quick and easy on the fuel rail, but besides that custom lines will be required to run this regulator.
