The Sealed Rail Diagnostic Package provides a simple and low-cost diagnostic capability for pumps and injectors on
Common Rail Systems made by all major manufacturers. Setting the benchmark for hydro-mechanical diagnostics, the Delphi Sealed Rail Kit provides simple, low-cost, on-vehicle test capability for all makes of Common Rail pumps and injectors.
The kit consists of an electronic pressure-tester and injector back-leakage measurement equipment, giving you the capability to isolate and check the actual Common Rail pump pressure, as well as identify individual faulty injectors. This means that only faulty components will need to be replaced. Don’t confuse the Delphi Sealed Rail Kit with a set of back-leak bottles.
Simple back-leak bottle sets only allow you to compare fuel return quantity between the injector; they cannot identify rail pressure or CR pump issues.
