Turbosmart Regulators

Turbosmart’s listings here are fuel pressure regulators with their fittings, filters and gauges, and the model number gives the fitting size. The FPR6, FPR8 and FPR10 have -6, -8 or -10 AN inlet, outlet and return ports and adjust from 35 to 80 psi. Their LP versions cover 3 to 20 psi for low-pressure and carburettor systems. The FPR12 Pro takes a -12 feed and return with 4 x -10 outlets, in an EFI version (50 to 130 psi) and an M version for mechanical pumps. The Kompact is the small option, with 1/8 NPT ports or as an in-rail replacement. Turbosmart states a 1:1 ratio, so with the reference port connected to the manifold, fuel pressure rises one-for-one with boost. Colours are black, blue, purple and red, plus an all-black Sleeper finish.

The supporting parts include adapters for mounting a regulator on factory fuel rails, and billet fuel filters with a 10 micron element in AN6, AN8 and AN10. Spare elements and brackets, a 0–100 psi gauge and a 90° 1/8 NPT adapter make up the rest.

Choose the size by the fuel lines and pump, and set the base pressure with the vacuum reference disconnected.
