2. INTRODUCTION
Designed to measure return fuel flow on diesel vehicles with up to 6 cylinders and fitted with common rail injection system. Identifies worn, blocked or
inoperative injectors, quickly and easily. The VS2048.V2 Master kit contains measurement tubes for short term tests and measurement bottles for
long term, more accurate evaluation. Includes range of adaptors to suit Bosch, Delphi and Denso injectors, for comprehensive coverage of common
rail diesel vehicles. The VS2046.V2 kit comprises measurement tubes and measurement bottles (for Bosch injectors). The VS2047.V2 comprises
adaptors for Bosch, Delphi and Denso injectors.
3. OPERATION
3.1. Most modern diesel vehicles are fitted with a sound deadening cowling over the top of the engine. If fitted, remove this cowling to gain
access to the engine.
3.2. Direct Connection Tubes (Bosch connectors only - see fig.1.5).
These tubes are ideal for a vehicle which will not start, and provide a very quick assessment.
3.2.1. The return pipes are retained by wire clips, remove the clips and store in a safe place. Gently ease out each of the return pipes from the
injectors (fig.2). Take care not to break the connectors as they can be brittle.
3.2.2. Plug the ends of the return pipes to avoid any spillage.
3.2.3. Connect the tubes to each injector (fig.3), the wire clips are not required as the return system is low pressure.
3.2.4. Crank over the engine until the tubes are at least 50% full. Take care, that should the engine start, the tubes will fill up very quickly.
3.2.5. Check the levels for each injector. The overall variation in the levels should be less than 10%. Any injector which has a back leakage problem
will have more diesel in the tube.
3.2.6. Remove the tubes from the injectors, taking care not to spill any diesel, place a finger over the end of the tube to hold the liquid in the tube
and then empty into a suitable container.
3.2.7. Refit the return pipes to the injectors and secure them with the wire clips as per the vehicle manufacturer's workshop manual.
