# Service bulletin 19\-FL\-001H

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10154683
- Published by NHTSA: 2019\-03\-18
- Manufacturer's number: 19\-FL\-001H
- Manufacturer's date: 2019\-02\-18
- NHTSA component: FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:INJECTORS; FUEL SYSTEM, GASOLINE

## NHTSA's summary

In a gasoline direct injection \(GDI\) engine, highly pressurized gasoline is injected via a common rail fuel line and injectors that deliver fuel directly into the combustion chamber of each cylinder. In comparison, in a conventional multi\-point fuel injection \(MPI\) engine, relatively low pressure gasoline is injected into the intake port of each cylinder. Due to high fuel pressures in a GDI system, servicing the GDI system requires special attention and handling procedures. This bulletin provides special service information and specification for the GDI fuel system components.
