This is the Turbosmart FPR-800 fuel pressure regulator. Turbosmart has manufactured this regulator out of billet aluminum where it is hand-assembled to allow for optimal precision. If you are making upwards of up to 800WHP, then you will need a regulator that can deliver the fuel needed to support that kind of power. The FPR-800 provides smooth and stable fuel pressure delivery under all conditions whether it be at idle or full throttle, and it will work with both manual or electric fuel pumps.
The FPR-800 features 1/8 NPT inlet (2) and outlet (1) ports, a 1/8 NPT gauge port, and it has a 30 to 70PSI base pressure adjustments along with a stable 1:1 ratio between fuel pressure and manifold pressure.
The FPR-800 will come supplied with a mounting bracket and hardware, along with a vacuum fitting and a gauge port blank. This particular regulator will come in a nice black finish to blend in with your engine bay.
