You should be able to use your original FPR that you removed when you installed the Comptech FPR.
Failing that, the AEM is a nice unit that bolts right up to the fuel rail and looks great in red.

The OEM fuel pressure is fine with an uprated fuel pump and the AEM controlling bigger injectors.
All FPRs increase fuel pressure with manifold pressure, it's just that the usual ratio is 1:1 (I believe) whereas the Comptech one is 10:1.
