Vortech Standard Fuel Management Unit 6:1 FMU 5/16" Barb Fittings 6Z110-140
6:1 Rising-Rate FMU for High-Output EFI Vortech Applications
The Vortech Standard Fuel Management Unit (FMU) (PN 6Z110-140) is a precision secondary fuel pressure regulator designed for multi-point electronic fuel injected (EFI) engines equipped with Vortech supercharger systems. This 6:1 rising-rate FMU installs inline with the factory fuel pressure regulator on the return line and increases fuel pressure in direct proportion to boost pressure, helping maintain safe air-to-fuel ratios under boost.
Proper operation assumes the fuel pump in use is capable of delivering sufficient pressure and flow as boost increases. Like all Vortech FMUs, this unit is CNC-machined from 6061-T6 aluminum and finished in a durable blue anodized coating for long-term reliability and corrosion resistance.
How the 6:1 FMU Calibration Is Used
The 6:1 FMU calibration is intended for high-output custom EFI applications where larger-than-stock fuel injectors are employed. This calibration provides a more moderate fuel pressure rise compared to higher-ratio FMUs, preventing excessive pressure while still supporting safe fueling under boost.
As an example, the 6:1 FMU is commonly used on Mustang applications with 30 lb/hr or 36 lb/hr injectors. Higher ratios (12:1, 10:1, 8:1, 7:1) are typically paired with stock or mildly upgraded injectors, while lower ratios (4:1 and 3:1) are reserved for even larger injector combinations.
Recommended Injector Pairings
- 12:1 - 19 lb/hr injectors
- 10:1 - 24 lb/hr injectors (Cobra)
- 8:1 - 24 lb/hr injectors (GT/LX)
- 6:1 - 30 lb/hr injectors
- 4:1 - 38-42 lb/hr injectors
- 3:1 - 50 lb/hr injectors
Injector Conversion Note: To convert injector size from cc/min to lb/hr, divide the cc value by 10.5 (example: 440cc ? 42 lb/hr).
