Fuel Rail Bleeding / Pressure Testing
All CFI engine fuel return hoses feature an inline Schrader
valve that can be used to bleed the fuel system pressure
and observe fuel system pressure when using the fuel
pressure gauge and specified adapter.
Fuel Pressure Gauge (PU-43506-A)
Fuel Pressure Gauge Adapters
• A = 314249 (.305-32 shallow core fitting/adapter
sup
plied with PU-43506-A Fuel Pressure Gauge)
• B = PS-48617 (.305-32 deep core fitting)
• C = PS-48762 (7/16-20 fitting)
1. Select the appropriate adapter.
2. Connect the adaptor to the fuel return hose Schrader
valve.
3. Connect the adapter to the fuel pressure/bleed tool
ga
uge.
4. To observe running fuel syst
em pressure, start the
engine and compare reading to the specification.
NOTE: Observe pressure reading at idle and whil
e
operating the vehicle.
