This new pump is capable of producing either vacuum or pressure with equal precision and convenience. The combination of dual-vacuum/pressure capability and powerful performance expands the applications of the pump to include turbo- and super-charger diagnostics, fluid transfer, windshield repair, cooling system pressure testing, and pressure brake bleeding. In addition to performance improvements, the look and feel of the pump has been updated. It fits more comfortably in the user’s hand, and both vacuum and pressure are created on the squeeze stroke for one-handed operation. Kit includes: Auto Test Kit; Kit includes everything for performing hundreds of automotive diagnostic & mechanical tests. Designed with proven features from the renowned Mityvac pumps, the MV8500 Silverline Elite Automotive Kit delivers both vacuum and pressure. Frequently Asked Questions: Q. Can the Mityvac MV8500 automotive test kit be used to test diesel engines? Includes:• Silverline Elite hand vacuum/pressure pump with 2" (50 mm) compound gauge with rubber boot

It is equipped with one finger pivoting lever action for vacuum and pressure release with minimum effort & equal accuracy. Designed with proven features from the renowned Mityvac pumps, the MV8500 Silverline Elite Automotive Kit delivers both vacuum and pressure. The dual capability of the Silverline hand pump combines two pumps into one. It will streamline your tool inventory while greatly extending its vehicle service applications.Testing a crankcase for leaks is certainly more helpful on 2 -strokes. However unless it is a higher end more expensive unit, then many times (at least for me) it's not worth the effort. The cost to repair many of the lower end unit can be prohibitive as many can be replaced for much less then the repair costs. On many of the lower end unit, parts may only be available as an assembly and not individually, making some simple repairs expensive ones. Your post seems to inidicate you need to research some basic engine functions for both 2-stroke and "4-mix" engines. None of us use combustion pressures as a reading - that's next to impossible for a bench mechanic. We use compression, leak-down and CC pressure/vacuum tests.
