Overview
The Works Engineering Stage 2 Fuel Pressure Regulator is a universal, adjustable return-line regulator CNC-machined from 6061-T6 billet aluminium. It mounts remotely on any fuel system with a return line and lets you dial base pressure from 20 psi up to the limit of your pump. Its boost-referenced 1:1 design raises fuel pressure in step with manifold boost so injectors stay correctly fuelled as the turbo spools.
Built for high-output naturally aspirated and forced-induction engines. The Stage 2 uses an internal double-diaphragm design for greater durability than the Stage 1 and adds interchangeable discharge ports to match the regulator's output to almost any fuel pump. A service port accepts a pressure gauge or can feed a nitrous/auxiliary-injector circuit.
