⚡ At a Glance
- • Pressure Range: Adjustable 20-120psi, original spring 20-75psi with replaceable spring to reach 75-120psi
- • Best for: Tuning enthusiasts and workshops needing adjustable EFI fuel pressure control
- • Not ideal for: Users seeking a plug-and-play, pre-fitted regulator for non-EFI systems
Bypass-return fuel regulator designed for aftermarket EFI applications. Extended adjustment capability is available through an internal spring replacement.
Consistent pressure under varying demand - with adjustable 20-120psi range
Spring-loaded regulation permits a set pressure across the bypass-return arrangement, with the supplied spring giving 20-75psi and an alternate top spring enabling 75-120psi. Mechanical adjustment of the spring preload changes the outlet pressure.
Precise pressure tuning keeps fuel delivery steady during high-load or modified-engine conditions, making calibration and mapping more predictable.
Works with multiple fuel types - with stated gasoline, E85 and alcohol compatibility
Compatibility is listed for gasoline, E85 and alcohol, indicating suitability for common petrol blends used in tuning and conversion projects. No additional fuel-specific conversions are specified in the description.
Allows flexibility when testing different fuels or running ethanol blends during performance tuning without sourcing a separate regulator for each fuel type.
Flexible fitment and monitoring - with three adapter sizes and an NPT gauge port
Three adapter sizes accommodate a range of fuel-hose diameters, and an NPT-threaded pressure-gauge port accepts a standard gauge for live readings. The description advises use of thread sealant tape when fitting the gauge.
Adapts to existing hose kits and permits direct pressure monitoring, simplifying diagnostics and setup on the dyno or at the roadside.
