The CNC-machined and anodised fuel rail kit by Adapt Motorsport is designed for Porsche 964 and 993 3.6ltr engines using the standard intake adaptors. It can also mount to Adapt Motorsport two-bolt adaptors for earlier 2.7, 3.0 and 3.2ltr Porsche 911 engines.
Fits
- Porsche 911 964 3.6L with standard intake adaptors
- Porsche 911 993 3.6L with standard intake adaptors
- Earlier Porsche 911 2.7L, 3.0L and 3.2L engines fitted with Adapt Motorsport two-bolt intake adaptors
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
This twin-rail kit provides configurable fuel connections using O-ring ports and AN-6 JIC fittings. It supports hose arrangements based on the factory 964 or 993 system, as well as a simplified dead-head configuration, and allows fuel-pressure sensing to be added for compatible aftermarket ECU tuning, data logging or protection strategies.
Functions
- Mounts directly to standard Porsche 964 and 993 intake adaptors
- Supports factory-style 964 or 993 fuel-hose layouts
- Allows a dead-head fuel-system arrangement
- Provides connection points for fuel-pressure sensing
- Uses removable fittings and plugs for flexible installation
Technical Details
- CNC-machined and anodised construction
- AN-6 JIC fittings with O-ring fuel-rail connections
- Product references: AMS9050032 and AMS9050033
- Kit includes two fuel rails
- Includes four ORB-to-JIC fittings, two ORB plugs and mounting screws for factory intake adaptors
- Cars with factory air-conditioning compressors must use the supplied plugs to close the rear ends of the rails and use a dead-head fuel-hose layout
Why Replacement Matters
This kit provides a serviceable and adaptable rail arrangement for compatible standard or modified fuel systems. Its interchangeable fittings and plugs allow the installation to be configured around the selected hose layout, intake adaptors and pressure-sensing requirements.
FAQs
- Can the kit reproduce the factory fuel layout? It can be arranged in a factory-style 964 or 993 configuration, or installed as a simplified dead-head system.

What This Product Does
The integrated Bosch regulator module controls fuel pressure while the damper helps suppress pressure waves created as the injectors open and close. Managing these pulsations supports more consistent fuel control and removes the need to mount separate regulator and damper units elsewhere in the fuel system.
Functions
- Distributes fuel to the engine’s injectors
- Regulates system pressure through a replaceable Bosch module
- Dampens injector-generated fuel-pressure pulsations
- Reduces the number of external fittings and hose connections
- Supports flexible custom fuel-line layouts
Technical Details
- Standard regulator pressure: 3.8 bar
- Alternative regulator pressures available from 3.0 to 4.0 bar
- Single configuration: one advanced rail with regulator and damper, plus one standard rail
- Dual configuration: two advanced rails with two regulators and dampers
- ORB ports use O-ring sealing and are supplied with AN6 JIC fittings and rail-end plugs
- Stated regulator flow capacity: 200 lph for a single regulator or 400 lph for the dual system
Why Replacement Matters
This system is intended for custom fuel-system installations where integrated pressure regulation and damping can provide a cleaner, less complex arrangement. The Bosch regulator modules are replaceable, allowing pressure specification changes or future servicing without replacing the complete rail assembly.
Installation Notes
- Custom-made fuel lines are required.
- The dual-regulator version requires a more complex hose arrangement than the single-regulator system.
- The manufacturer states that a Bosch 044 pump’s 275 lph flow exceeds the 200 lph limit of a single regulator; the complete fuel-system specification must therefore be matched to the selected configuration.
- Fasteners and manifold adapters are included when the Carrera 3.2 version is selected.
FAQs
- Can the regulator be replaced?
Yes. The kit uses replaceable Bosch regulator modules, allowing servicing or a change to another available pressure rating. - What is the difference between the single and dual versions?
The single version combines one advanced regulator-and-damper rail with one standard rail. The dual version uses two advanced rails and provides a stated combined regulator capacity of 400 lph. - Are standard Porsche fuel lines retained?
No. Adapt Motorsport specifies that custom-made fuel lines are required for this kit.
