Fuel Injection / Collection Rail

The Adapt Motorsport Advanced Fuel Rail Kit combines fuel distribution, Bosch pressure regulation and pulse damping for Porsche 911 Carrera 3.2 applications. It is offered in single- and dual-regulator configurations for custom fuel-system installations.

Fits:

• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50

What This Product Does

Opening and closing fuel injectors generate pressure pulses within the fuel circuit. The integrated damper helps control these fluctuations, while the replaceable Bosch module regulates rail pressure. Combining these components within the rail reduces the need to mount separate regulator and damper units, simplifying the number of hoses and connections required.

Functions

• Distributes fuel between the engine injectors
• Controls rail pressure through a replaceable Bosch regulator module
• Helps suppress pressure pulses created by injector operation
• Reduces the number of external fittings and potential leakage points
• Allows the fuel-hose layout to be tailored to the installation

Technical Details

• Available for Carrera 3.2 manifolds 
• Supplied with a 3.8-bar regulator.
• Single version pairs one regulator-and-damper rail with one conventional fuel rail
• Dual version uses two rails, each incorporating its own regulator and damper
• Rated regulator flow is 200 lph per module, giving a combined 400 lph with the dual arrangement
• ORB ports use O-ring seals; AN6 JIC unions and end plugs are included, with fasteners and manifold adapters supplied for the Carrera 3.2 option

Why Replacement Matters

This kit is intended for bespoke or upgraded fuel systems where integrated pressure management can make the installation more compact and easier to service. The Bosch modules can be removed independently, allowing a worn regulator to be renewed or the pressure specification to be changed without replacing the complete rail.

Installation Notes

• Bespoke fuel hoses must be made to suit the vehicle and selected configuration
• The dual-regulator layout requires additional hose routing compared with the single version
• Each regulator is limited to 200 lph; a Bosch 044 pump is stated at 275 lph and therefore exceeds the capacity of one regulator
• Pump output, injector requirements and regulator capacity must be considered together when specifying the complete system

FAQs

• Is the pressure regulator serviceable?
  Yes. The rail accepts replaceable Bosch regulator modules, so the module can be renewed separately.
• How do the two kit layouts differ?
  The single arrangement includes one integrated rail and one standard rail. The dual arrangement employs two integrated rails for a combined regulator rating of 400 lph.
• Will the original fuel hoses fit?
  No. Custom hoses are necessary for installation.
• Can a different operating pressure be selected?
  Yes. The normal specification is 3.8 bar, with regulator options stated from 3.0 to 4.0 bar.

Check fitment for your specific vehicle, engine and planned fuel-system configuration before ordering.
