    Hello AM, I have BBK fuel rails and need a regulator, the BBK Regulator seems to have not so good reviews...will this work with BBK rails? Thanks, 1990 mustang 5.0

    JimN

    • The Kirban Billet Adjustable Fuel Regulator would be compatible with the BBK Fuel Rails, as well as any other fuel rails that accept stock style regulators.

    Is this the same thing as a "voltage regulator"?

    JuanC

    • No, the Kirban Billet Adjustable Fuel Regulator regulates the amount of fuel pressure that your Mustang is running. A voltage regulator regulates the voltage coming from your alternator.

    Is there an access port to tap for a fuel gauge?

    ShiftyG

    • This Fuel Regulator does not have an access port for a fuel gauge. I suggest attaching the gauge to the schrader valve.

      Kirban adjustable fuel pressure regulator

      I really like that its billet, well built, nice looking piece. It’s easy to adjust, works great and looks great too! I’ve only had it on my car for about a week but so far working well and doing what it’s suppose to do! For the price and looks and build it’s unbeatable! My install time was due to the fact I did not take off upper intake, only took off throttle bracket for cable. It’s hard but can be done.

      Best bang for the buck

      Good quality, great price. Easiest install is to take upper intake off then disconnect fuel rails and remove rails to properly get to regulator Allen key bolts. Takes more time but is much easier in the long run. Will take about 1.5hrs for average "mustang head".

      Budget build

      I have not used this product yet. It is installed on my motor that on an engine stand. This isn't the first adjustable fuel pressure regulator that I have used but it is the sweetest looking one I've purchased. I bought it because of how low they advertise the fuel pressure can be adjusted to. On a 306 cube motor with 24lb injectors you don't need a lot of pressure. When I do get my motor going I write another review

      What the truth needed

      I have fuel injection pressure problems with my 1992 Ford truck (302 engine). I am running duel tanks and fuel pumps. I installed a fuel pressure gauge and discovered both pumps run below 40 psi. I then installed the Kirban fuel regulator in about 2 hours, adjusted the fuel pressure to 40 psi, and the truck ran as good as it ever has. One of my fuel pumps could not supply the 40 psi required (new Autozone pump). I will replace with a Motorcraft pump and test the system.

      This is a very nice quality piece, very well made and super easy to install, I used this with bbk high flow rails and fit perfectly. One thing I would add is it's been nice if it had a port for a guage. Other than that great piece.

      Solved my high RPM stumbles

      Have been looking for a cure for a high RPM stumble I have had for over a year. After replacing alot of other items, this finally solved it. The other FPRs would have also done the same, but I liked the billet extruded look of this one most.
