Vortech Super Fuel Management Unit (FMU) 6X100-001
Rising-Rate Fuel Pressure Regulator for Supercharged Applications
The Vortech Super Fuel Management Unit (PN 6X100-001) is a rising-rate fuel pressure regulator designed to provide additional fuel under boost in supercharged applications. Commonly referred to as an FMU, this unit increases fuel pressure in relation to boost pressure, helping maintain safe air/fuel ratios on systems that retain factory-style fuel injection and engine management.
This FMU is frequently used in entry-level and legacy Vortech supercharger systems where additional fueling is required without converting to larger injectors or aftermarket engine management. As boost increases, the FMU proportionally raises fuel pressure to supply the extra fuel demanded by forced induction.
How the Vortech FMU Works
The Vortech FMU operates as a boost-referenced, rising-rate regulator. Under vacuum and low-load conditions, fuel pressure remains near stock levels for normal drivability. As boost builds, the FMU increases fuel pressure at a predetermined rate relative to manifold pressure, ensuring adequate fuel delivery during wide-open throttle and boost conditions.
This approach allows supercharged vehicles to maintain stock-like behavior off boost while providing the additional fuel required when the supercharger is producing pressure.
Typical Applications
- Vortech entry-level and H.O. supercharger systems
- Factory EFI vehicles retaining stock injectors
- Street-driven supercharged applications with moderate boost levels
- Legacy Vortech systems originally engineered around FMU-based fueling

FAQs
- What does an FMU do?
An FMU increases fuel pressure in relation to boost pressure, supplying additional fuel when a supercharger is producing boost. - Is an FMU a replacement for custom tuning?
No. FMUs are typically used on legacy or entry-level systems. Modern high-power builds usually rely on larger injectors and ECU tuning.
