4. Use a suitable tool in order to measure the
combined flow of both outlets with a stopwatch.
Fuel flow should be a minimum of 2 L/min
(0.53 US gpm).
5. If the combined flow is less than 2 L/min
(0.53 US gpm), replace the pump.
6. Reconnect the outlet lines in the correct positions.
7. Start the engine and check for any leakage of fuel
or air from the fuel lines.
Check the Function of the Pressure
Regulator
1. Remove the fuel line from fuel outlet (A) for the
supply to the fuel injection pump.
2. Install a suitable pipe with a tap for a pressure
gauge. Connect a 0 to 80 kPa (0 to 12 psi)
pressure gauge.
Note: One end of the pipe must be blanked.
3. Energize the fuel transfer pump for two minutes in
order to remove any trapped air.
4. Record the pressure reading at high idle. The
minimum pressure reading should be the following
values:
All Fuel Injection Pumps
Low idle ................................. 25 kPa (3.6 psi)
High idle ................................ 25 kPa (3.6 psi)
Note: The maximum pressure for the fuel injection
pump at idle speed or rated speed is 75 kPa
(10.9 psi).
5. Reconnect the fuel line. Energize the fuel transfer
pump for two minutes in order to remove any
trapped air.
Check for the following issues if the pressures are
outside of the above specifications.
•
All electrical connections are installed correctly.
•
There are no leaks in the fuel lines or connections.
•
The O-ring on the fuel filter housing (2) does not
leak.
