Has almost everything needed for just about any diesel engine, including my Bobcat tractor. The only item I wished it had would be a 90° elbow to reach cylinder blocked by other engine compartment walls and such. There is so much brass at the attachment end of the gauge hose that you loses several inches of clearance space.
But it works flawlessly and I’m very pleased with it.

I wouldn't bother purchasing this compression tester. The one I received had many problems. The gauge wouldn't hold air. The hoses arent crimped tight enough. When threaded in a spark plug hole and trying to remove, the hose just rotates freely and the threaded portion stays in the plug hole. Looks good, but junk.
