Expanding on our very successful intake and fuel system parts, we have launched our advanced fuel management system for classic 911s. With built in fuel pressure regulator and dampers, this reduces the need for separate regulator and damper units, greatly simplifying and reducing the cost of fuel fittings and hose arrangements. Less fittings, means less risk for leaks, and ultimately a safer fueling solution.
The Bosch regulator modules can easily be changed to different rated pressures, or replaced, making the units serviceable on top of the long lasting and proven design.
Fuel pressure waves in fuel systems are caused by the opening and closing of the injectors can create destructive pressure waves at the injector nozzle, resulting in odd tuning characteristics. The damper assists in arresting the waves, reducing their impact and allowing accurate fuel control into the intake system.
We are the only manufacturer offering built in regulators and damping systems for the highest caliber fuel solutions.
Advantages
- Reduced fittings and hosing and labour costs and simplified hose layouts
- Reduced potential for leak points
- Serviceable, replaceable off the shelf Bosch parts
- Direct fit to 3.2/964/993
- ORB fittings with O rings for neat and leak free performance.
- Supplied with AN6 JIC fittings and plugs for rail ends
- Fasteners and adapters for 3.2 if selected
Available in 2 versions,
- One advanced fuel rail with regulator and damper in one rail, and one standard fuel rail,
- Two advanced fuel rails with dual regulators and dampers, for big horsepower applications. (photos to be uploaded)
The units are available for both 964/993 manifolds, to which also suits all of our adapter kits, and a different 3.2 Carrera manifold kit. All units come with a 3.8bar standard regulator, other pressures available, from 3.0 to 4.0 bar, please confirm with us if different pressure required.
Notes
Requires custom made fuel lines, the dual regulator system requires slightly more complex hosing than the single system.
The Bosch fuel pressure regulator is limited to 200lph fuel flow, after this point, it begins to choke, causing the pressure to increase. Two regulators means double the flow, so 400lph flow rates. For reference a Bosch 044 fuel pump is 275lph, too large for a single Bosch regulator.
- 200lph allows for approximately 390Hp on E85, or 475Hp on 98 fuel.
- 400lph allows for approximately 780Hp on E85 or 950Hp on 98 fuel.
This version of the fuel rail uses our proprietary outlet fitting to AN6. This outlet fitting is steel, and protected with a Black Nickel coating. This can not be changed, future versions of the rail will use standard AN6 adapters.
