Fuel rails / regulators


- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC
Adjustable fuel pressure regulator with JIC / AN fittings. Porsche 911 EFI upgrade
Fits:
Porsche 911 - 1974 to 1983 (CIS to EFI upgrade)
This is the Motorsport/Custom version of our fuel pressure regulator that uses AN6 JIC fittings and plugs to suit aftermarket fuel lines and fuel rail configurations when converting from CIS to EFI, or removing the later model fuel injection systems for an alternative custom setup.
Our adjustable fuel pressure regulator uses the latest Bosch regulators and is adjustable from 2.0 to 5.0 Bar pressures. This simple and elegant design uses O-Ring boss sealing adapters to the manifold with multiple options for hose connections. Ultimate hose layout flexibility is achieved through multiple port orientations and options so this allows for standard 3.2, 964, or 993 fuel hose configurations, or, for dead head configurations where there is a single feed line to each fuel rail and no return line from the rail, only this regulator.
Easy to replace regulator with Bosch OEM reliability
3 outlet ports for flexible hose, fitting, gauge, sensor port options - now or for the future
This kit is perfect for any EFI conversion on any of the air cooled 6 cylinder engines. These can be combined with our fuel rails that fit to either our 2 bolt adapters, or the 964/993 intake stacks
The Bosch regulator is rated to a maximum fuel flow of 200lpm. The adjustable pressure regulator flows more, but we have not yet measured its upper limits, but it has been proven to work with a Bosch 044 fuel pump.
Kit Includes:
- Fuel pressure regulator body x 1
- 2.0 to 5.0 adjustable fuel pressure regulator instead of fixed regulator x 1
- AN6 JIC fittings x 4
- ORB Plugs x 2
Applications
Any custom hose solution with AN/JIC Fittings for any vehicle with custom hosing and mounting.
Any 911 2.7/3.0 when removing the CIS and installing your own EFI solution.

Our newly released fuel pressure regulator brackets mount to the Adapt Motorsport fuel pressure regulators to the engine breather cover bolts on top of the classic aircooled engines.
The same as Porsche do for the 964.
Manufactured from CNC machine aluminium and anodised in a dark silver colour, they really add a nice look to any classic Porsche engine bay.
Please Note
Only the regulator brackets and fasteners are included in the kit, the regulator is shown for reference purposes only and not included.
