Folks, I've had a number of inquiries about this injector cleaner.
Based on a Google search "Bosch 'EFP 60 A' "
http://www.google.com/search?hl=en&lr=&q=+bosch+%22efep+60+A%22 it appears that this is also capable of handling diesel injectors, a pleasant surprise.
However, you would need to replace the current pressure gauge that is capable of handling the higher pressures and I can't speak to using it for diesel injectors because I used it exclusively for gasoline injectors.
The newer model from Bosch is the EFEP 67 D as a reference
