Full model list at the end of this description.

## ⚙️ Key Features

-   Marked part not sold, so not available separately
-   0.680 kg
-   39 applications on the V series
-   Fuel System group

## 🔌 Function

Distributes pressurised fuel to each injector and holds them in position, giving every cylinder the same supply pressure.

## ⚠️ Common Signs of Failure

-   Fuel smell in the engine bay or fuel staining along the rail
-   Weeping at an injector bore or a rail union
-   Hard hot starting or a rail that will not hold pressure
-   Injector bores scored, corroded or ovalled
-   Rail body cracked or its mounting points distorted

## 🛠️ Service Notes

-   This number is marked as not sold, so ask what larger assembly supplies it before committing to the job
-   Rail 3809500 is the other rail listed here, at 2.472 kg on the D series, and is not an alternative to this one
-   Prove the rail leak-free under pressure before running, since fuel escaping in an enclosed engine space is a fire risk
