      How would you install a fuel gauge on the FPR, since it does not come with an adapter.

      • This Billet Adjustable Fuel Regulator does not have provisions for a fuel pressure gauge.

      Helpful (0)

      Does this regulator increase fuel pressure 1:1 when the vacuum port is subjected to positive pressure (ie boost) like a stock one will?

      • Hi, This Kirban Billet Adjustable Fuel Regulator works just like a stock regulator and will increase fuel pressure when under pressure.

      Helpful (0)

      If you don't have a fuel pressure gauge, what would be the easiest way to check the psi?

      • The safest and best method I found to check the fuel pressure is to use a separate fuel pressure tester; I got the Actron model #CP7838 tester from Summit. It has all the adapters you'll need and is straightforward to use. Just read and follow the directions; it works well. You attach it to the Schrader valve on the fuel rail. The guy at AM recommended this to me rather than using a permanently installed pressure gauge, which could be unsafe.

          Beautiful regulator

          Purchased this regulator for my 1995 mustang w/308 bottom end with a downs ford boxed upper and gt40 lower. Sadly this regulator does not fit. The downs ford upper box intake manifold bows out to much that even after grinding 1/2” out of the intake it still didn’t fit. I used the regulator on a different car and it worked flawless on a cobra intake.

          Kirban fuel pressure regulator

          Awesome product so far. Used this part on a 96 f150 with a 351. I just installed gt40 heads and an e303 cam. After bumping up the fuel pressure a few pounds, my lean codes stopped and the truck runs amazing. Took about to 10 minutes to install and adjust. Fits the stock fuel rails on a 92-96 ford truck and bronco with a 351. May also fit trucks with a 302 but not sure. Would highly recomend

          Great

          My car had gt40 intake manifold, bbk cai, throttle body, and msd ignition. My car was pulling okay, but it liked to bog down. I thought it was fuel, so I purchased this. I had it installed and tuned in less than an hour, and it completely solved my problem. Great product, fast shipping! AM is the best!

          Good product

          Had to pull the GT40 tubular intake to get the second screw out of the existing BBK regulator. After doing all that, it popped right on, and was done very quickly. I may have been able to do it without removing the intake, but got frustrated quickly after trying 5 times.

          An okay choice

          I just replaced my second Kirban Fuel regulator with the Aeromotive regulator. I installed my first Kirban regulator in late 2002 when I did a Bullitt intake and PI head swap. In 2009 that unit finally failed. I replaced it with he same piece. This second unit failed last month, September 2014. I decided to go with the Aeromotive unit this time. We will see how it holds up. All of these regulators are very easy to install and adjust. You will need to be able to read the fuel pressure. I have a small gauge permanently installed on my fuel rail which really makes it easy. Install and adjustment takes no more than 10 minutes. Quality is good and fit is perfect. Performance gains are only really related to the other modifications performed. This part will help you get the correct fuel pressure to best utilize your other modifications and is a must if moving to larger injectors.

          Good adjustable regulator

          The Kirban adjustable fuel pressure regulator is an excellent unit; well made and easy to install and adjust. After adjusting to 46 psi at the track, my 96 GT gained at least one tenth second and eliminated the "flat spot" that was occurring above 5500 rpm. Excellent product!

          exactly what I needed

          I upgraded my fuel injectors from 24lb to 30lb. The standard Mustang fuel regulator is 30lb. I kept receiving a "lean" engine code. After installing, the race shop that installed it found the optimum pressure was 38lbs. My Cobra runs fantastic! This regulator is very similar to the orginal and very easy to adjust. This product functions exactly as advertised and is well worth the money.

          Adjustable Fuel Regulator

          Seems to be a good product so far. Hope it last longer than one year like the cheap ones you get from your local parts store. I'm impressed with the construction of the regulator.

          Fits nice, super easy install and looks great

          I replaced my original regulator since it was giving me pressure problems. A year or so after I installed my 255lph fuel pump my reg went. I hear its very common when upgrading the fuel pump that the regulator looses its calibration. Good product works as advertised, installed without having to take anything off other than the old part and accurately adjusts and holds pressure. I recommend!

          Best Fuel Pressure Regulator

          I bought this Kirban Performance fuel pressure regulator, a few weeks ago, and installation is simple, all you have to do is adjust it with the vaccum line off, it's that simple, any time you need to adjust the fuel pressure, all you have to do is turn the screw on the top of it, it is so easy, as long as you have an on rail fuel pressure gauge.
