We now offer a bespoke billet fuel rail for the BMW M20 engine. This rail requires no modification to work with the factory intake manifold and standard 14mm style fuel injectors. The factory fuel rail clips can be retained assuming the chosen injectors support them as well. This rail features a 14mm bore through the entirety of the rail. There will be no flow limitations using this rail over the factory rail at any power level. The inlet and outlet ports are both -8 ORB. Installation of the rail can be completed with the intake manifold still installed on the engine. This rail is designed and manufactured with both attention to detail and functionality in mind, it is truly a product second to none.
The rail is machined from solid 6061-T6. This is not made from extruded stock like most rails on the market. The rail is finished in a vapor-blast and black anodize process. The finishing processes result in a satin black exterior which aids in scratch resistance, keeping the part looking fresh.
The rail comes with new fasteners for use during installation. Fuel injectors and fittings are not included.
Some details to note about this rail:
- The rail is gauged at those making higher power levels, thus it is not designed to be used with a factory fuel regulator.
- Factory fuel lines will not directly connect to this rail as it utilizes -8 ORB ports and is designed to be used with AN hoses.
- It is advisable to always use high-performance PTFE lined AN hose when building a fuel system for a car.
- We use -ORB hose ends with our own installs as it is a more compact solution that using adapters and standard hose ends.
