Tomei Fuel Pressure Regulator Adapter



  • Q: Perrin top feed fuel lines will this work?  Chuckless126492021 year ago

    I’m running top feed Perrin fuel lines with the fuel pressure regulator bolt in plate. It says to use a stock fuel pressure regulator but I want to run aftermarket. Would this adapter allow me to bolt it as well as the fpr to the plate of the Perrin lines?

      A:  This would be only confirmed fitment for the stock fuel pressure regulator. You could try reaching out to Tomei to see if this is something that could work however.

  • Q: Do I need another fitting?  4 years ago

    I purchased this adaptor along with the Tomei type S fpr. Is there another fitting need to hook the 2 together? The fpr came with 2 fittings where I can hook up fuel lines but I'll need 3 to make this work, from my understanding. '02 WRX.

      A:  You will need a 1/8NPT fitting in order to connect a fuel line to to this adapter, and you should be able to use fitting part number TOM 185103.

  • Q: Adapter  John M6 years ago

    Instead of using it for a fuel pressure regulator, could you install a fuel pressure sender in its place?

      A:  Due to the fitting size, it would not just bolt right in. Also this would block off your return system.

  • Q: 2007 STi   05_wrex6 years ago

    The description states this will fit a 2007the STi. But the engine list under subaru does not include an ej257, only ej255. I just ordered this so I hope it fits.
  • Q: Will this make the regulator fit the stock rail on 04 wrx  bjadrian23394177 years ago

    Is this the adaptor that will let the regulator fit onto the stock rail on a 2004 wrx. And then you just adjust the pressure to 43.5 with the vacuum line off? or do you have to create a whole new fuel system with this?
    • 1 of 1 people found the following answer helpful

      A:  Yes, this will allow you to adapt your stock rails to accept a threaded fitting fuel line. That should make it easier to hook up a fuel pressure regulator.
