The BLOX Racing FMU is designed for use on fuel injected, forced induction vehicles using the OEM electronic engine management system. As with any forced induction application, additional fuel is required for the engine to operate properly and make maximum power. The BLOX Racing FMU will increase the engine’s fuel pressure, as the pressure in the intake manifold increases.

Key Features

• Adjustable Base Pressure: Turn the adjustment knob to set base fuel pressure from 30-70 PSI precisely tuning to your injectors pump and engine setup.
• Complete Kit with Fittings: Includes -6AN fittings fuel line adapters mounting bracket and hardware for direct bolt-on installation without additional parts.
• 12:1 Rising Rate Ratio: Increases fuel pressure 12 PSI per 1 PSI of boost for matched fueling with turbochargers or superchargers keeping air fuel ratios stable across RPM range.
• Billet 6061-T6 Aluminum Construction: CNC machined body resists corrosion and withstands high pressures up to 150 PSI for long-term durability in harsh engine bays.
• Pair with adjustable fuel pressure regulator for full control over base and boost pressures.
• Packed in protective foam insert box dimensions 6.25 x 5.5 x 3 inches.
