Flow meter for Common Rail injection systems like Volkswagen TDI.

Easy and quick testing of return flow from each injector. Test connection via return pipe from injector/s.

2 way of test are possible - long time test with bowls, connection from test tube with return exit of injector.

Otherwise with the included "quick test" - direkt connection from small test cylinder with return flow of injecter.

Both methods make your diesel diagnostics very quick and save - no more required to test each injector separately with unit injector tester / UI .
