The FTF EFI Fuel Pressure Regulator is a billet-aluminium, adjustable regulator for electronic fuel injection systems, with two -AN10 inlet ports and a -AN6 return, adjustable across 33-87 PSI (2.3-6.0 Bar).
Overview
Designed for EFI fuel systems running higher rail pressures, this regulator gives fine control over fuel delivery so injectors see consistent, stable pressure under load. Fully reusable AN fitting construction means lines can be rebuilt across multiple builds rather than replacing fittings each time.
Specifications
- Application: EFI
- Minimum Pressure: 33 PSI / 2.3 Bar
- Maximum Pressure: 87 PSI / 6.0 Bar
- Inlet Port Size: 2 x AN10
- Return Port Size: AN6
- Gauge Port Size: 1/8" NPT
Key Features
- Fully reusable AN fitting design - rebuild lines without replacing fittings
- Compatible with fuel, oil, coolant, and hydraulic fluid systems
- Proven in racing and high-performance builds
- Precision-engineered for leak-free sealing
Who It's For
Suited to EFI-equipped restomods, street/strip builds, and performance engine swaps running higher fuel rail pressures than a stock system, where a fixed-pressure OEM regulator won't allow tuning.
FAQ
Is this regulator suitable for carburetted engines?
No - at 33-87 PSI this regulator is built for EFI (fuel-injected) systems. A carburetted engine needs a much lower pressure regulator, such as the FueLab 51503 (4-12 PSI) or 51505 (1-3 PSI).
What gauge port does it use?
A 1/8" NPT gauge port, so a standard mechanical or electronic fuel pressure gauge fits directly to the regulator.
