The advance test plugs are used to connect pressure-measuring equipment to the automatic advance system of CAV/Lucas/Delphi diesel injection pumps.
Where are they fitted?
The test plug is installed in place of the original advance pressure end plug, located at the pressure end of the pump's automatic advance housing.
The procedure is straightforward:
- Stop the test bench.
- Remove the original advance pressure end plug.
- Fit the appropriate test plug.
- Connect it to a pressure gauge using a suitable fuel connection.
This allows pressure measurements to be taken during the advance testing procedure.
