Fuel Rail: Description and Operation



Fuel Rail





Each fuel rail maintains a fuel pressure of typically 4.5bar (65 psi), however, this pressure will vary depending on engine requirements; lower at idle, higher at full load. Four fuel injectors are installed in each intercooler adapter and are connected to the fuel rail. 'O' ring seals are used to seal the injectors in the fuel rails and the intercooler adapters.

A fuel pressure damper is attached to each of the fuel rails.
