            This regulator does not fit a standard foxbody. The vacuum port interferes with the EGR valve. The vacuum port can not be rotated, which the tech could not answer.

            Excellent product!

            The regulator bolts up very easily if you are doing this with an injector swap, or at least with the upper intake and throttle body off. Highly recommend a 2" male male extension and a female female coupler in 1/8" npt if you are installing a fuel pressure gauge along with it. This fit well with the egr still in place, but proves to be a tight fit.

            great FPR!

            I usually by BBK, but my tuner recommended aeromotive so I went with it. Setup was super easy and I had it connected in no time. Pretty much plug and play. I highly recommend it and it looks great!
