This regulator is intended only for installations using the threaded lower return connection. It is not suitable for vehicles fitted with the 5/16" hose-barb connection at the bottom of the regulator.
Check fitment for your specific vehicle (model, year, engine) before ordering. Previous repairs may have introduced a different regulator or hose arrangement, so compare the installed connection with this M14 version.
What This Product Does
The regulator controls fuel pressure within the injection system. Its adjustable mechanism allows pressure to be configured for the relevant standard application or for a compatible tuned installation requiring a different setting.
Functions
- Attaches directly to the original fuel rail through an O-ring connection
- Provides adjustable pressure between 2.0 and 5.0 bar
- Connects to the fuel return line through an M14 threaded fitting
- Permits pressure adjustment for compatible Porsche 944 Turbo tuning configurations
- Replaces specified Porsche and Bosch fixed-pressure regulators
Technical Details
- Pressure adjustment range: 2.0–5.0 bar
- Fuel return connection: M14 threaded outlet fitting
- Fuel-rail connection: direct O-ring mounting
- Kit includes the regulator body, adjustable regulator, M14 outlet fitting, cap screws and lock washers
- Tested by Adapt Motorsport with Bosch 044 fuel pumps; the maximum supported flow rate has not been established
- Supplied without a preset pressure setting
Symptoms of Fault
- Fuel leaking from the original regulator
- Engine running problems associated with incorrect or unstable fuel pressure
- Difficulty obtaining the required pressure during tuning or diagnosis
Why Replacement Matters
Many original regulators are now affected by age-related leakage or failure. This adjustable unit renews the pressure-control component while retaining direct fitment to the applicable factory rail. After installation, pressure must be measured and set on the vehicle to the specification required by its engine and fuel system.

FAQs
- Is the regulator supplied pre-set?
No. It must be adjusted after installation using an appropriate fuel-pressure gauge and fittings for the factory rail. - Can it be used with a Bosch 044 fuel pump?
Adapt Motorsport has tested it with Bosch 044 pumps, but the upper flow limit has not been determined. - Will it fit a hose-barb return connection?
No. This version uses an M14 threaded outlet and is not suitable for the regulator arrangement with a 5/16" lower barb. - Should the installed regulator be checked before ordering?
Yes. Earlier repairs may have changed the regulator, hoses or connection type from the original vehicle specification.
