The Adapt Motorsport Advanced Fuel Rail Kit integrates fuel-pressure regulation and damping for Porsche 964 and 993 applications. It simplifies custom fuel-hose arrangements by reducing the number of separate components, fittings and potential leak points.

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.
