Compression tester set up for testing. The hose is screwed into a glow plug hole after removing a glow plug. Note: This is a mock up to illustrate the tester placement, but this is a tester for a gasoline engine, not a diesel because it only goes up to 300 psi. A diesel tester would go up to 1000 psi. Also, ALL of the glow plugs should be removed, not just one. In addition, the hose is not actually screwed in because the fitting is the wrong size. (Photo/ Phil Decker)
