Cleanfire Fuel Injection
Fuel Rail Bleeding / Pressure Testing
Some models feature a Schrader valve located on the
pump flange assembly (PFA) that can be used to bleed or
test the fuel system pressure when using the fuel pressure
gauge and specified adapter.
2013 models do not feature a Schrader valve on the pump
flan
ge assembly (PFA). Install the Fuel Line Adapter to
bleed and test fuel pressure.
Fuel Pressure Gauge (PU-43506-A)
Fuel Pressure Gauge Adapters (PFA with Schrader Valve)
• A = 314249 (.305-32 shallow core fitting/adapter
supp
lied with PU-43506-A Fuel Pressure Gauge)
• B = PS-48617 (.305-32 deep core fitting)
• C = PS-48762 (7/16-20 fitting)
Fuel Line Adapter (PFA without Schrader Valve)
• D = PA-48838 (Fuel Line Adapter)
1. Select the appropriate adapter.
2. Connect the adaptor to the Schrader valve.
3. On models that require the Fuel Line Adapter tool,
rem
ove the RETURN fuel hose from the pump flange.
4. Install the Fuel Line adapter tool on to the fitting.
Co
nnect the other end of the tool to the fuel hose.
5. Connect the adapter to the fu
el pressure/bleed tool
gauge.
6. To observe running fuel system pressure, start the
eng
ine and compare reading to the specification.
