To Test Warm Control Pressure:
1. Reconnect wiring to warm-up regulator and auxiliary air
valve.
2. Open valve on Test Hose.
3. Start engine and run for specified time.
4. Compare Warm Control pressure readings with
manufacturer’s specifications.
To Test System Pressure:
1. Test can be performed with engine cold or warm.
2. Reconnect wiring to warm-up regulator and auxiliary air
valve.
3. Close valve on Test Hose (closed valve eliminates
control pressure.)
4. Start engine and run for specified time.
5. Compare System Pressure reading with
manufacturer’s specifications.
To Test Rest Pressure:
1. Open valve on Test Hose.
2. With engine at normal operating temperature, energize
fuel pump or start engine.
3. Turn engine off or disable pump when pressure
reading stabilizes.
4. Compare pressure readings taken at specified time
intervals with manufacturer’s specifications.
5. If the Rest Pressure drops too quickly, check for leaks
at o-ring and fuel line connections.
6. If no external leaks are found, consult the service
manual for causes of low fuel pressure.
To Test Fuel Delivery Rate:
1. If pressure testing finds no problems in the fuel
injection system, the fuel pump should be checked.
2. Consult manufacturer’s specifications for the correct
fuel volume and time period to test.
3. Hook up the Test Gauge for a pressure test and put
the bleed-off tube into a graduated container.
4. Start the engine or activate the fuel pump.
5. Collect fuel in the container for the specified period of
time. Compare the volume of fuel collected with the
manufacturer’s specifications.
6. Turn off the engine or disconnect the fuel pump.
To Complete Testing:
1. Deactivate fuel pump and relieve fuel system
pressure. With ignition off, put Test Gauge bleed-off
tube in a disposal container and press bleed valve on
the Test Gauge. The fuel will drain into the container.
2. Remove Test Gauge. Reconnect all fuel lines and any
vacuum lines or wiring connectors that were
disconnected.
3. Start engine and check for fuel system leaks.
