Pressure Valves / Sensors / Dampers / Regulators
Fits:
Porsche 944 - 1982 to 1985
Porsche 924S - 1981 to 1984
Cars with M44.02 / M44.04 engines
Replaces Porsche part number 944 110 198 01 for Porsche 944 '82 to '85 with the M44.02 and M44.04 engines. 2.5 bar base fuel pressure.
Replacement for Bosch 0 280 160 214
Direct replacement for the OEM Bosch fuel pressure regulators on the Porsche 944 and some other makes and models. Most of these regulators are original and now nearly 40 years old so they are prone to leak or fail causing all sorts of running and tuning issues.
To suit the lower operating fuel pressure of the 3.2 Motronic, we use an adjustable fuel pressure regulator. This simple and elegant design uses steel O-Ring boss sealing adapters to the manifold.
Easily replaceable fuel pressure regulator.
Spare outlet for fuel pressure gauge or sensor.
The adjustable fuel pressure regulator has been tested with Bosch 044 fuel pumps, but the upper limit of fuel flow rate has not been tested.
Kit Includes:
Porsche 944 OEM fitting kit - SPA Adjustable fuel pressure regulator
Fuel pressure regulator body x 1
2.0 to 5.0 adjustable fuel pressure regulator instead of fixed regulator x 1
Adapter fittings to fit OEM hose and fuel rail ends x 1
Hose Tail fitting to fit factory return line x 1
ORB Plug x 2
Applications
This kit must use the adjustable fuel pressure regulator as Bosch does not produce a standard 2.5bar pressure regulator in this form.
Please Note
We have also developed fuel pressure dampers for the 3.2 and 928 engines, check out our site for the product details.
The fuel pressure regulator needs to be adjusted and set on the car after installation to ensure the operating conditions meet the factory specifications. A fuel pressure gauge and fittings to adapt to the factory fuel rails is required to be able to complete this procedure. The regulators are not shipped pre-set to the 2.5bar operating pressure.
We also list the 944 fuel pressure damper as a direct replacement.

Fuel Pressure Valves, Sensors, Dampers & Regulators – Consistent Fuel Flow for Porsche Performance
Fuel pressure valves, sensors, dampers, and regulators are critical components in your Porsche’s fuel system, ensuring stable fuel pressure and accurate fuel delivery under all driving conditions. Working together, these parts maintain the delicate balance between performance, efficiency, and emissions control that defines Porsche engineering.
At Design911, we offer a comprehensive range of fuel pressure components — including regulators, dampers, pressure relief valves, and sensors — developed to deliver exceptional reliability and precise fitment for Porsche models across generations. Crafted from high-strength alloys, corrosion-resistant materials, and advanced electronics, our components ensure smooth operation and long service life, even under high heat and vibration.
Whether you’re maintaining a modern 992 or restoring a classic 911, these manufacturer-quality components are essential for achieving consistent fuel delivery and flawless performance.
What Do Fuel Pressure Valves, Sensors & Regulators Do?
These components ensure that the engine receives the correct fuel pressure to maintain stable combustion, power output, and throttle response.
Core Functions:
- Fuel
Pressure Regulator: Maintains steady pressure in the fuel rail to
match engine demand.
- Pressure
Sensor: Monitors and relays fuel pressure data to the ECU for precise
adjustments.
- Fuel
Damper: Smooths out fuel pulses and pressure fluctuations.
- Pressure Valve: Prevents over-pressurisation, protecting the fuel system.
Together, they ensure smooth idling, responsive acceleration, and consistent power delivery — key for both performance and fuel economy.
Why Do Fuel Pressure Components Fail?
Due to constant exposure to heat, vibration, and fuel contaminants, these components can wear out over time, leading to erratic fuel pressure and performance issues.
Common Causes of Failure Include:
- Clogging
or contamination from dirty fuel or debris.
- Internal
diaphragm wear in regulators or dampers.
- Corrosion
from moisture or ethanol-based fuels.
- Electrical
failure in pressure sensors.
- Vacuum leaks causing incorrect fuel pressure readings.
Symptoms of failure include rough idling, poor acceleration, stalling, fuel odours, or a check engine light indicating a pressure-related fault.
Why Replace the Fuel Pressure Components?
Replacing worn or malfunctioning fuel pressure components restores proper system regulation, improving performance, fuel efficiency, and drivability. Our precision-fit, manufacturer-quality replacements are built for accuracy and durability, ensuring long-term reliability.
Key Benefits:
- Restores stable fuel pressure and consistent delivery.
- Improves performance, acceleration, and throttle response.
- Reduces fuel consumption and emissions.
- Prevents damage to injectors and fuel pumps.
- Crafted from corrosion-resistant, heat-tolerant materials.
- Direct-fit compatibility for Porsche models of all eras.
Ideal for regular maintenance, rebuilds, and performance upgrades, these components ensure your Porsche operates with the precision it was designed for.
Highlights:
- Comprehensive selection of Porsche fuel pressure regulators, valves, dampers, and sensors.
- Precision-engineered for exact pressure control and reliability.
- Durable construction for long service life.
- Ensures stable fuel delivery and efficient combustion.
- Perfect for performance tuning, restorations, or maintenance.
- Compatible with classic and modern Porsche models
