Fuel for the Four Cylinders
The fuel rail is the backbone of the fuel supply on the EFI conversion of your M102. It holds the four injectors, keeps them cleanly positioned over the intake ports and distributes the fuel from the pressure regulator evenly to all cylinders. Fits the M102 8V as well as the 16V in the Mercedes 190E.
When switching from KE-Jetronic to free injection the rail replaces the mechanical fuel distributor circuit. The injectors sit firmly and sealed so the ECU can control the injected quantity precisely via the opening times.
Compatibility
- 190E 1.8 (W201)
- 190E 2.0 (W201)

- 190E 2.5-16 (W201)

The whole conversion is also available as a complete package. Take a look at the EFI Kit for the M102 8V or the M102 16V.
Note
The fuel rail is part of an EFI conversion and requires an ECU, wiring harness and matching injectors.
