Fuel Rail Bleeding

The 2007 600 CFI units will have one of two different styles of
Schrader valves.
A shallow core valve (1) and will use the adapter that comes with
the fuel pressure gauge (PN PV-43506-A).
A deep core valve (2) will need the adapter PN PS-48167.

The fuel pressure gauge (PN PV-43506-A) is used to check or
bleed the pressure in the fuel rail lines. You will need to bleed
off the fuel pressure if any service is needed to the fuel system
or if engine is to be removed.
1. Select the appropriate adapter for your valve type.
• Adapter (3) is used on the shallow core valve.
• Adapter (4) is used on the deep core valve.

2. Attach the correct gauge to the valve on the fuel pressure
tool.
3. Once the gauge is onto the Schrader valve, the pressure
gauge will indicate the pressure in the fuel rail.
4. To bleed the pressure from the fuel rail, you can turn the
bleeder valve on the gauge and bleed the system safely.
5. At this point the fuel rail is ready for service.
