This Adapt Motorsport fixed 3.0 bar fuel pressure regulator kit is a direct-fit solution for the early 1987 Porsche 928 S4. It may also be used as a pressure upgrade for the 1984–89 Porsche 911 Carrera 3.2 and 1980–86 non-CIS 928 when accompanied by suitable engine-management retuning.
Fits:
- Porsche 911 1984-1986 3.2L - upgrade from 2.5 to 3.0 bar; retuning required
- Porsche 911 1987-1989 3.2L G50 - upgrade from 2.5 to 3.0 bar; retuning required
- Porsche 928S4 5.0L 1987
What This Product Does
The regulator maintains a fixed 3.0 bar fuel pressure without a connected vacuum reference line. The supplied body and adapters allow the Bosch regulator to connect to the relevant factory fuel rail, supply hose and return line.
Functions
- Controls fuel-system pressure at a fixed 3.0 bar setting
- Connects the Bosch regulator to the original fuel rail and hose ends
- Retains connection to the factory fuel return line
- Provides a replacement for the specified Porsche and Bosch references
- Supports suitably retuned 2.5-to-3.0 bar upgrade applications
Technical Details
- Regulator type: fixed-pressure Bosch unit
- Nominal pressure: 3.0 bar
- Vacuum reference: no vacuum line connected
- Kit contents: one regulator body, one Bosch regulator, two OEM-end adapter fittings, one return-line hose-tail fitting and one ORB plug
- Porsche reference: 92811019802
- Bosch references: 0280160232 and 0280160262
Symptoms of Fault
- Difficult starting when the engine is hot
- Rough, unstable or hunting idle
- Rich running, black exhaust smoke or increased fuel consumption
- Hesitation when applying the throttle
- Misfiring or weak running under load
- Fuel odour or leakage near the regulator
- Fuel pressure that is incorrect, unstable or falls too quickly after shutdown
Why Replacement Matters
An ageing or defective regulator can allow fuel pressure to move outside the intended specification, affecting starting, idle quality and fuelling. This Porsche-specific fitting kit provides the components needed to install a modern fixed-pressure Bosch regulator while retaining the relevant factory hose, rail and return-line connections. On vehicles originally configured for 2.5 bar, the change to 3.0 bar must be matched by appropriate chip or ECU retuning rather than treated as a direct standard-pressure replacement.
FAQs
- Is this a direct replacement for every listed model?
No. It is specified as a direct 3.0 bar replacement for the early 1987 non-CIS Porsche 928. Earlier 928 and 911 Carrera 3.2 applications require retuning. - Can it replace Porsche reference 92811019802?
Yes. This reference is specified for the 3.0 bar application without a connected vacuum line. - Which Bosch regulators does the kit replace?
The stated cross-references are Bosch 0280160232 and 0280160262. - Is the regulator adjustable?
No. The included Bosch regulator has a fixed 3.0 bar pressure specification. - Does the kit connect to the factory return line?
Yes. A hose-tail fitting for the original return line is included. - Is specialist installation recommended?
Professional installation and calibration are advisable, particularly when converting a vehicle from 2.5 to 3.0 bar fuel pressure.

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
