            Great product

            This regulator gets the job done and is simple to install/adjust. Good from my car being lightly modded to my now 650whp car.

            Good Product

            The FPR seems to be working great since install. No leaks and car is running good. I will mention that the stock hardware is very hard to screw into the bottom of the regulator. Especially when you are using a small Hex Key to do so.

            Easy and efficient

            I bought the bbk fuel pressure regulator si that I can control the amount of fuel I get for my foxbody, it took me about an hour to install it, including taking off the upper intake manifold, installing the new fpr and new injectors and putting everything back together. Overall impressed and definitely recommend using this product for anyone best bang for your buck.

            Great part for any setup

            This is a great part for any setup whether it be a full blown race car or a daily driver with bolt-ons. Very easily adjustable, I would reccomend a pressure gauge to set pressure but after that it's smooh sailing!!!

            great upgrade!!!

            My stock regulator went out on me and this was a perfect upgrade!!! You will need Teflon tape to seal the cap if you don't use a gauge, and you will want to have a pressure gauge handy to set the pressure after install because there aren't any instructions on how to set the pressure.
